So what to do if you are in the middle of a fantastic gig and suddenly an alarm sounds reporting that 'a situation has been reported' and that you should make your way to the nearest exit?
Do you leave cursing the fact they haven't yet played your favourite song or stay in the hope it's an elaborate part of the act?
That was exactly the conundrum facing hundreds at The Nick Rayns LCR, at Norwich's University of East Anglia last night, as the Miles Kane gig ended in slightly chaotic and surreal scenes.
The Liverpudlian singer was mid-way through his encore when the alarm sounded.
Unfortunately it wasn't an example of the singer's Scouse humour and eventually the 700-plus crowd made their way to the exits - facing disappointment at having missed out on his traditional set closer 'Come Closer'.
Yet, ten minutes later, Kane and his band were given the all-clear to return to the stage and see out their set.
After joking that 'bloody students' had presumably set off an alarm he finished with a rounding 'Come Closer' to a half-full but very appreciative venue.
Prior to that 27-year-old Kane, whose previous band credits include The Rascals and Last of the Shadow Puppets (with Alex Turner From The Arctic Monkeys) impressed with his back catalogue of punchy, tub-thumping rock and roll tunes.
In the flesh Kane is one of those artists whose songs step up a level - and a lot of that is to do with his flair as a frontman - all charm, wit and cheeky smiles. At times he's more than similar to a Jam-era Paul Weller, spitting out his lyrics while impressively wielding his guitar.
Highlights are the songs you can sing along to - and many do. A feisty Inhaler, Rearrange and She's Taking Over see a good proportion of the crowd swarm to the front to pogo along.
In spite of the rather farcical proceedings, the stand-out proves to be the call-to-arms Come Closer with its rousing 'ahs' and 'oohs' which I'm sure will be an earworm for anyone who did stay for at least the next week.
Note: Support was provided by The Family Rain, three brothers whose bluesy rock is a perfect start to the evening. Hotly-tipped they prove popular with the large audience who have arrived early to see them play. Well worth checking out.
