oh, well...... i think seeing U2 at murrayfield on the Joshua Tree tour in 1987 would be it
fantastic day, support bands were Runrig, Love and Money, The Misson and the Pogues (with Kirsty McColl)
I was 15 and in love and had travelled form Inverness to see them (with no way of getting home and nowhere to stay over either!!)
was a great gig, at that young impressionable age when i believe music could change teh world and i had all the answers!!!
close second was going to see Bg country in Dublin - it was the second last gig they did before stuart adamson died. I was in dublin to watch Scotland v Ireland at football, i didn't even know they were playing, met their accountant in a bar and he took me to the gig - ended up on stage at the end of the gig
