Singing is fun and should be enjoyable for those performing and (optionally) those listening
I can't sing for toffee (I was in the school choir, mainly because I actually did sing), but myself and a couple of mates did the "band" thing, we even got paid a few times (no, not to stop playing)!
There is (was hopefully, my Korean ex. had it) a karaoke tape of me duetting Wild Thing with the marketing director of Pfizer Korea!
