My wife and I frequent Karaoke bars a lot, we both sing, though, compared to her I suck!
My wife can sing damn near ANYTHING...
here is a link to her youtube site with a few vids i made with background songs being sung by her.
http://www.youtube.com/libbyreinhartGranted, shes a bit more serious about music than many karaoke patrons (she is working on some original songs for a Demo CD)
As for me? I tend to sing jsut about anything Josh Turner
A Bit of Brad Paisely (Ticks, Whiskey Lullaby (with my wife), Mud on the Tires, and Im Still a Guy)
Also a bit of Alan Jackson.
My Wife and I also sing : lets make love, and Broken (seether&Amy Lee)
I do it for fun, so does my wife, but she is pursuing a musical career.. ill stick to web design and flying lol
