For me it would be the Gun Club back in '85. Met Patricia Morrison in the bar at the back of the venue and proceed to attempt to impress her with our (that would myself and The Boss from MOTH) knowledge of the late 70's LA punk scene, which she'd been a part of whilst in the Bags. Anyway she very kindly offered to put us on the guest list for a gig that weekend in Sheffield (not far from where we were based in Leeds). I still feel somewhat embarrassed looking back at how much we must have overstayed our welcome in the dressing room at that show. After barging in at the end of their set, they were clearly in no mood hob-nobbing with us (and several other hangers-on we'd brought with us) specially after we'd helped ourselves to their beer and sandwiches. However, Patricia was very tolerent and The late, great Jeffrey Lee Pierce managed a few grunts as I recall..and that's about it really. Not a very interesting story I'm afraid!
Oh! did meet the Ramones after a gig in '79 whilst I was still at school and got them to sign a record sleeeve, that I still have.
