Oh yeah, you can also stake out the karaoke bars to find a singer! Some of those folks are actually pretty good and are already totally comfortable and so enthusiastic about singing that they are actually karaoke regulars, getting better every time, not just drunk folks singing once in a while for the heck of it on the spur of the moment.
My singer is soooo enthusiastic about singing, which is a great thing, and if we're not practicing, he can be found at karaoke! He even bought this new karaoke machine for $20 at Wal-mart the other day and it is KILLER. Lately, we've been having unplugged rehearsals over at his house just so he can be by his karaoke machine with the words on the screen.

listen to the songs together over and over. (I play on the couch arm
