On the 19th of November, American metalcore band The Ghost Inside was involved in a very serious bus accident that killed their bus driver as well as the driver of the truck that hit them, and left several members of the band seriously injured. The alternative scene immediately united to raise money for the medical bills and, last week, a charity gig was announced to support them. It was to feature Deaf Havana, Your Demise and You Me At Six at the Underworld in London. Tickets sold out in forty five seconds and I was one of the lucky few who snatched one of them.

The night opened with Norwich based outfit Deaf Havana, who have just made their come back after being nowhere to be heard for about a year. The Underworld (which is a six hundred capacity venue, very small by the standards of every band on the bill tonight) is already fully packed when they come on, and their energetic, yet nostalgic brand of alternative rock is the perfect way to start the evening. The singalongs are plenty, especially during The World or Nothing, known by everyone in the building, the super catchy 22 (extracted from the band's latest record, 2013's Old Souls) or Anemophobia, a song that can speak to virtually anyone. Their half hour long set, along with the shadow of their comeback, sets a celebratory mood in the place – a mood that will not budge an inch all evening.

A couple of years ago, there was no way you could attend a gig without spotting someone sporting Your Demise merch. Their signature designs (the three bands printed with the outfit's name and the target over teenage Justin Bieber's face) were nothing short of iconic, and Your Demise were a household name in the scene, having toured with the likes of A Day To Remember or Bring Me The Horizon. The band announced their split in 2013, played their last ever show at the very same Underworld in March 2014 and when tonight's line up was announced and their name came up, the members made it clear – the 11^th of December was a one off.

Just like with every other band on the bill, it was never about who played a quality set and who would be a band to watch. Yesterday was only about raising as much money as possible for The Ghost Inside. Though, as far as one-off gigs go, Your Demise have played a fairly awesome one and I would frankly describe their set as absolutely flawless. They drove the crowd absolutely mental, crowdsurfing, moshing, dancing and singing your heart out was pretty much compulsory, and on stage, it was like this little breaking up thing had never happened. Vocalist Ed McRae was incredibly charismatic as always, all the members' big smiles were infectious and closing track The Kids We Used To Be, sang by an ecstatic crowd, may or may not have brought a tear to my eye.

I suppose this is how you become a legendary band.

Headliners You Me At Six have started their phenomenal career ten years ago and, since then, they have been from strength to strength. The little band from Surrey who sported Glamour Kills tops and sang about girls and partying have made it big, reaching a number one spot in the charts with their latest album (2014's Cavalier Youth) and selling out various arenas all over the United Kingdom. Seeing them play a venue as tiny as the Underworld is nothing short of miraculous for the English guys are now, pretty much rockstars – just without the egos.

In May 2015, they had headlined Slam Dunk Festival and dedicated a large part of their set to tracks from their debut album, the classic Take Off Your Colours (come on, who in this scene hasn't had "Take off your colours, who are you wearing them for?" or "So who's keeping score on who is a whore?" as a status on social media?), to celebrate the tenth anniversary of their career, and even though only one song of this album (The Truth is a Terrible Thing) will be played tonight, their Underworld set felt like a celebration in the exact same way. Whether the songs are extracted from their early days (such as Underdog or Stay With Me, both from 2010's excellent Hold Me Down) or from their most recent albums, the crowd is just as responsive, shouting every word and causing mayhem all over the place. The singalongs, notably during Liquid Confidence, are deafening.

Not many bands would have jumped at the opportunity of playing a small room once they would have reached the arenas, but it seems like to You Me At Six, it was the most natural thing in the world to do. Every single one of frontman Josh Franceschi's interventions is dedicated to The Ghost Inside and filled with a sincerity that is sadly missed in our world. The guys seems just as confortable on a tiny stage as they do on a massive one and it is during gigs like these that you realise that You Me At Six truly are the boys next door who made it big but will always come back to their roots when asked. Closing track Bite My Tongue, introduced by Josh as their "heaviest song" and dedicated to all the heavy bands in our scene, simply set the room on fire and put an end to a night to remember.

This gig was never about bands making themselves noticed for their artistic qualities, but if it had been, all three would have battled for the title of best band of the evening for they were all simply excellent in their own, unique way.

This gig was about raising as much money as possible for The Ghost Inside and showing, one more time, that this scene is a beautiful little world. It is flawed and it has its bad people, but overall, it has the capacity of standing together to pick the others up from the ground. Tonight was a much needed reminder that the alternative scene has a sense of family like none other, and in times like these, every little demonstration of generosity and love is important.

I also wish the speediest recovery and send all my love and positive thoughts to the guys in The Ghost Inside. I hope we made you proud.
