If you dump enough booze into me, I could be convinced to sing these at a karaoke bar:

I'm not sure if I would sing very well drunk, I sing well when I'm not drunk.. but I love to sing.. I would definitely sing these with some alcohol in me.

I'll Be by Edwin McCain

Come onnnn.. it's such a 90s ballad that I could envision myself singing completely and totally drunk.. swaying and all.. trying to coerce the rest of the karaoke bar to sing along with me.

I Will Remember You by Sarah McLachlan

Again.. similar effect as 'I'll Be'.. with the exception that I would probably use my arms to make many a drunken hand gestures.. I can see this happening as well.

La Vie Boheme by RENT

I would sing the entire soundtrack. Beginning to end.. I would love to sing 'Light My Candle' with male accompaniment. I absolutely love the fun-ness of 'La Vie Boheme' though. Seems like a good drunken song.
