Here's an excerpt transcribed from a sample, of DON'T MAKE ME SING ALONG sung by Al Simmons on the various-artists album "Toddler's Next Steps: Singalong Songs" (2002). No songwriter is credited at Allmusic.com:

…Don't make me sing along.
When you perform your song,
Please do it on your own.
Leave the audience alone.
Keep the entertainment on the stage
Because that's where it belongs.
Keep the house lights low.
I'm not in the show,
So don't make me sing along.

[SPOKEN:] Everybody now!*….

[* Yes, I'm aware of the irony.]
