I couldn't track down the lyrics either. Wasn't it Douglas Byng who had the big hit with it? A gay friend who has been known to appear in drag as "Ruby Snatch" does the bit quoted but I'm not sure if he knows any other verses. He's a colleague of my wife's and she helped him get made up for their office Xmas show. "I never thought I'd hear myself say at work :'Get your trousers off and I'll help you on with your tights'" she told me later!
