A few years ago I had a similar experience with a song that I loved to sing ( still do), but the first time I sang it was terrible..I told a little story before the song and generally thought I did a good job for it being the first time in public. It went down like a lead turd in a porcelain piss pot ( if you can excuse the analogy). Anyway, being the tenacious devil that I am I sang it the following night to a different audience in a different city, the trepidation I felt actually detracted the performance, but the small but enthusiastic audience really enjoyed it...go figure!The thing is If you enjoy it, do it ( to paraphrase that nice chap Mr. Crowely)
