@StirlingEgg from what I can see JSBX were at he Garage in '99. I think I saw them at the QMU in '02, so you're way ahead of me there; and that was my first gig in 9 years. (I'd got into 90s music, but just me and never thought to go.)
The start of my mid-life crisis if you like 😂 So I did go to the student's union with some new alt pals, but ironically one of our party, a day short of his 18th was refused. Sad but funny, and we love to remind him. The upstairs gallery was fairly empty except for a lovely pregnant lass giving her well underage wean a grand night out.
