A while ago I posted some video links from different cartoons that had a recycling theme and song. Here are some more links. You might not think this would be relevant to the RE3.org demographic but some of the cartoons are 3-4 years old and high school and college age students can reminisce about watching them. Read some of the comments and you will get that feel.
Kappa Mikey sings the Recycle Song (What is Kappa Mikey?)
Bloo and June sing the same song (from the Cartoon Network)
You might remember this song from an earlier post, however it was in German.
