In terms of gigs I missed...
Any XTC gig in their formative years
Thin Lizzy at the Cardiff Capitol 1978, shortly before its demolition (it was a planning thing, nothing to do with Lizzy)
MC5 at York Rowing Club, circa 1972. I'm told this happened, but I've been unable to prove it!
And those I'd like to revisit...
Pub rock special at Guildford Civic Hall 1974ish, Feelgoods second on the bill
Ramones/Talking Heads/Saints at the Roundhouse 1977. Wow!
Happy daze
