Couldn't stand it. Had to look it up. I'm so AR. It's karaoke.
As for doing it, no, I live in a small town and have never been to a karaoke bar. But I WOULD sing, under the right circumstances. I "can't carry a tune in a bucket" as my grandma would say, but I make up in volume what I lack in talent.
Once, when I was in a college Elementary Music class, we had to learn to play either the guitar or the piano. I chose the guitar (because I already knew, from piano lessons when I was young, that I couldn't do two things with two different hands at the same time on the piano). Our "recital" was a group rendition of "Row, Row, Row Your Boat." My group of six dwindled away to nothing about halfway through, so I just got louder and louder as each voice drifted off, and finished the song all by myself. I SHOULD have been embarrassed.
Nowadays, my fifth graders look at me like I'm nuts when I sing Happy Birthday. I really, REALLY can't sing. I even use that as a threat to get them back on task . . . "If you don't get that done and get it done right now, I'm going to SING -- to YOU -- in front of EVERYBODY!" Sometimes it actually works.
