Perhaps I should clarify. Just because I *do* Karaoke, doesn't mean I'm particularly good at it. I would never attempt "Africa" on my own. I reserve this song for Piss Cakes or a large group of us go up and and "gang sing" it. I could never nail the vocals on "Africa" - but it just happens to be one of me and my friends all time favorite songs. It's kind of our anthem, so we go for it. Typically, patrons think we're idiots, and they're ususally right.
My girlfriend likes to do Little Red Corvette, so if you ever see a dirty blonde gettin' down and some dude, chuggin tequila shots, thats us!
Livin' on a Prayer - Bon Jovi. Easy to sing. Hit 'em with the oh wa oh wa oh wa thing at the beginning and get easy laughs to get the crowd going. Then throw in a couple power fists and the crowd goes wild. Also works really well if you get a couple other dudes up there with you.
