Well here it is. I had several requests! When we would perform this as kids, all we did was sway back and forth and clap, but we knew every single word. Hopefully my brothers won't kill me for posting it (better to ask forgiveness than permission in this case). Nichole was a baby when we performed this song, so her talent during this performance was laughing her head off, you can hear her laughing the hardest on this video.
