I unabashedly love karaoke! My absolute favorite song to do is "Kiss", not the Prince original which is way too high for my voice, but the Tom Jones/Art of Noise version. I kick ass at singing that song if I do say so myself.
I'm also pretty good with Bad Company's "Feel Like Making Love". And I once rocked the house at a bar in a small Alabama town singing "Cradle of Love" by Billy Idol. I literally had people coming up to me and shaking my hand after that one.
