I didn't want to draw attention to this, since it would have prompted people asking to trade, and I don't do trades, and the only way I would know of to put it on youtube would be to point a camera at the TV screen while playing it, but last january I actually found a copy of Let's Learn to Play Together. It was a bit weird watching it without the system, so I'm glad that the person who uploaded it used the system, so I could view it a bit differently (without the system, the first choice is always chosen, and the on-screen graphics that appear during games don't appear, making it very confusing). The back of the box mentions other releases, with images and descriptions, and there is one Sesame Street release that wasn't uploaded, Let's Play School.
Still, I don't think Let's Learn to Play Together was very good, despite the presence of Forgetful Jones and Don Music, or the fact that hardly any of the clips were released elsewhere on video or DVD (including a few that I hadn't heard of, such as That's What Counts with the Count - which does have a page at Muppet Wiki - and Bubbles, Bubbles, Bubbles with Snuffy - which doesn't have a wiki page). Due to the interactive nature of the program, the results of helping Don Music write asong aren't as funny as the results of Kermit helping him write a song.
