I just came upon this thread - interestingly the same thing happened to me, not long ago, and it was the same song. I only play "Seven Drunken Nights" when it's requested and I didn't know about the part where the audience shouts "you bitch....". A wedding party came in and wanted to hear it and the drunken bride got angry because I didn't pause long enough for them to shout these words. Although I was a good sport and went along with them (I know I'm there to entertain and I do so to the best of my ability) I have to say that I hated every minute of it. I found the group truly repulsive (including and especially the bride and groom) and just found myself wondering why adults get such a kick out of something so ...I don't even know what to call it...pathetic?? What a thrill - we got to yell out naughty words in a pub!!!!
