If you have the nerve to get up and sing, then do it!!

You'll likely sound awful to begin with, but practice and practice works, we all started somewhere, I know I wasn't born with THAT perfect singing voice, practice over the years has made it far better. Can you imagine if I hadn't bothered in the first place, the thought makes me shiver, as I do enjoy singing.

Exactly!
