PLEASE don't make me do a sing-along!!!

Is it bad that I can't stand a singalong?

OK, I feel like I terrible mother. I brought my 5 month-old daughter to a new play group this week and ten minutes into the session the child care professional running the group brings out his guitar. I need to explain that my husband plays the guitar for our child all the time. But he makes up lyrics that tend to go like this:

Lizzie Lizzie Lizzie-Lou. You're the one that makes the poo.....

....and so on and so forth. (This is an improvement from lyrics he used to make up before Lizzie was born that usually found himself trying to find words that rhymed with bobbies, vagina and butt.) No matter what he comes up with it's always hysterical and I end up crying with laughter. I look forward to his jam sessions, you never know what he'll come up with next. "Hey Katie! What rhymes with smelly diaper?" would not be an unusual request.

Anyway, I'm getting away from myself. The childcare professional grabs his guitar and I get excited thinking he's going to sing some fun made-up song for the kids. And then it happened. As soon as he sang the opening word of "Itsy Bitsy Spider" every mom starts to sing along. I broke out in a cold sweat. I HATE sing-alongs. PLEASE PLEASE PLEASE DON'T MAKE ME SING ALONG WITH THESE WOMEN!

I can't explain it. Being forced to sing in public with strangers just makes me feel icky all over. Does this make me bad person? I feel that there's just something wrong with twelve women clapping along to "The wheels on the bus" while their barely sitting-up children sit there looking completely overstimulated. I know there's a million developmental benefits of singing along with your child. And I do sing to my kid. Between her father and me she gets sung to most of the day. But they're songs that don't make sense even if they do rhyme. And at least it's just Lizzie hearing me, I can sing whatever I want.
