The “AB” was where I summoned an entourage of old Engineering/Science schools flat mates, and fellow Law undergrads for my 21st birthday bash. Best pint of bitter in Brum at the time, October 1979. Used to pop in there before gigs at Barbarella’s off Broad Street (sadly also gone), including (mainly) punk bands, The Clash, The Jam, Blondie, etc.; or Odeon gigs, inc. Frank Zappa, BB King (supported by the Wilko Johnson Band, recently split from Dr Feelgood.)
Unfortunately, I was living off Wake Green Road in Moseley at the time: it was piddling down with rain and there was a bus-strike on…. I imagined that no one would bother turning up in those circs, so stayed in my freezing gaff.
Apparently, the place was rammed and they all told me they’d had a great time…. Better than if I’d actually been there! Caused a lot of mirth for the rest of the academic year.
