I think it was STEPS. I vividly remember we had seats 5 6 7 and 8 which was presumably quite the LOL.
I would count my "first" though as first after I properly got into music circa 03, and I'm not sure who it would be - probably Showgirl Homecoming OR The Sweet Escape Tour, both in 07.
My first "adult" concert (without my parents) was Fall Out Boy/Gym Class Hereos/Cute Is What We Aim For. Weirdly the Arctic Monkeys were the opening act
1. Madonna Wembley 87
2. Five Star Portsmouth Guildhall 88
3. Bananarama Southampton Guildhall 89
4. Madonna Wembley 90
5. CAN'T REMEMBER BUT IT MIGHT HAVE BEEN MADONNA 93 WEMBLEY, SO LET'S GO WITH THAT, BUT IT DEFINITELY WASN'T CHAKA DEMUS AND PLIERS
Depends. My first gig that was "just" a gig was Ride and the Glasgow QMU in 1990. However, I have been reminded that the Nolans headlined the Super Summer Special show we went to in Scarborough in 1981. I assert that they were simply last on a mixed bill of entertainers rather than a full-scale headlining Nolans concert. They didn't play any more than 4 or 5 songs. That's not a gig, that's a PA.
STEPS in Wembley around 98/99 with my parents. First time with a friend was in think MIKA in Brighton '07. He filled the arena cos he's so quirky like.
Thank goodness I was too drunk to remember, but I too have seen bands at the QMU and well before Madge (never thought I'd say those words again - I hated both Glasgow uni venues for going out though, I was such a music snob in those days )
I can't remember the first gig I saw without being taken by my parents. My mum took me to the Dooleys concert, and to my first few Bucks Fizz concerts. Then I remember going to see Gary Numan with my cousin Jayne (not a fan myself, but she was supposed to be going with her boyfriend who dumped her). By the mid 80s I was going with my friend Peter though. I think it may have been a-ha at the Bristol Hippodrome.
