Just Say No song - help me!

I love Punky, and I think the episode Just Say No in season 2, which focuses on peer pressure and encouraging children to say no to drugs. One may argue that the plot itself with the sixth-grade girls offering Punky and Cherie drugs from a large, varied stash of pills and joints may not be completely realistic, but I still think it is great. And of course it could be realistic, but the point is not how it happens, but to show how Punky and Cherie did not succumb to peer pressure, even if it would mean getting kicked out of a really "cool" group.

Anyway, at the end of the episode you see real-life footage of the parades held throughout America on April 26, 1985 to encourage kids to Just Say No to drugs, following the 80's nationwide Just Say No anti-drug campaign. It particularly shows the parade in Atlanta, Georgia which Soleil Moon Frye leads at the age of 8½, and tells that Cherie Johnson also held a parade, in California.

During these clips, a song (probably called Just Say No, I think:S ) is played. I absolutely love that song, it's sooo great!!! Does anyone know who sings that particular version? And if you can find it, buy it or download it somewhere?? (Or maybe someone could send it?) I would really appreciate it!!
