If I had a decent voice, or if I didn't have a performance-crippling fear of singing to a bunch of faces that are staring at me blankly, and if I had at least 4 beers in my system...I would totally sing the song "Hot Child In The City" by Nick Gilder. If they didn't have that song available, I'd sing "The Warrior" by Scandal, and I would hope that my current love interest was in the audience so I could do the little "Bang! Bang!" signal directly to him, followed by a wink.
But I don't have a decent voice, and I'm too terrified to relax on stage and instead of singing anything awesome, I always end up crackling out a shitty, forgettable rendition of something safe like "Daydream Believer."
One of these days I'll grow a pair and actually attempt to nail one of my karaoke fantasies. Until then, I am sticking to the AM Gold classics.
