Back in the day I used to spend up to 5 nights a week in the Astoria, or, more specifically, the Keith Moon bar, blagging drinks from PR types and engaging in banter with members of Coldlay and The Wildhearts. I couldn't stomach that place, post-smoking ban. It was too heavy, man. I do not miss it.
As for the Metro, Crack Village played their first gig there, as part of me and Wade's "Saturday Spitroast" night. The PA was a disgrace, and we ended up having a massive fight with the guy running the venue, who was a gigantic puckering arsehole. Awesome gig though. I still have it, on VHS. Ikara Colt, Erol Alkan, The 80s Matchbox all came down and danced, and we gave everyone who came in the building a free tequila shot. We knew how to throw parties in those days.
