That's fantastic. Suspect there's a New Hormones re-use of moribund Buzzcocks publicity going on there. The Beach Club was based in a club just up from Victoria, so that may have been where you found it?
Could be.. IIRC it was a late Victorian building that had a big open central area that housed a sort of antique market.
I actually found 3 or 4 of the Buzzcocks posters. All re-used for the Beach club, which I think by that time had closed. Gave the rest away to other Buzzcocks fans.
