You haven't seen devotion till you've been to Ultimate Power, where over 1000 people come together to roar along to the music of Journey and co. Dig out your finest '80s gear, warm up those vocal chords and prepare to do your best Bonnie Tyler impression as you join the crowds, belting out tunes by the likes of Meat Loaf, Aerosmith and Bon Jovi. Over 18s only. Arrive before midnight.
