What better way to sing Christmas carols in public but not sound terrible? Hide yourself in a group so you don’t stand out. Chances are there are going to be a few just as bad (or worse) than you anyway. Just tone it down a bit when you get to the high notes so you don’t blow your cover.
Freethunk Admin: Except for “Silent Night.” There’s no way to hide your voice with that carol–if you’re out of tune, you’re screwed.
