If this is any consolation to you mate I had the same trouble at the beginning of the 90s where exactly the same thing happened, cracking venue, big turnout and one stupid drunken so called mate effing and blinding over the mic saying I was a fanny for not using cd's ect, at the end of the night he was out of it so in the morning I went round to his house gave him his cut and told him to f*** off, you have my 100% support on this even though I don't know you personaly
