I like Karaoke. I don't really mind when people can't carry a tune, either. And I think the drunks who applaud them are expressing human kindness, which is too frequently inevident in the world today. One of the most affecting vocal performances I have ever seen was by a middleaged woman who sang "I Will Alway Love You" completely out of tune, tears running down her cheeks. She meant it, which is more than I can say for a lot of professional musicians I have heard.
So my advice to Skipy is to have a couple of drinks. Maybe the alcohol will help kill the bug you've got up your butt. Then get up there and sing "Hound Dog".
