On tour with SkinTrade back in the early 90s we played Lincoln, travelling up from Bath at 7am. We were drinking Special Brew from then. By the time we came to go on they had to prop me up against the fire exit. I recall Tony crawling around onstage on his hands & knees because he'd dropped a pick! We were awful but sold a lot of merchandise that night because the audience were under the misguided impression we were like the Sex Pistols and the Who rolled into one. We weren't the new messiah, we were very naughty boys!
That was the worst although I fell off stage in Nottingham Dec '94 through drink. I tend to do drunken gigs far less now but certainly had my fair share back in the day.
