From the 1990 TV special Cartoon All-Stars to the Rescue," this catchy anti-drug ditty Wonderful Ways to Say No" (1990), posted to YouTube by a fan of famed Disney lyricist Howard Ashman (The Little Mermaid, Aladdin, etc):
Here's "Wonderful Ways to Say No" from the multi-network drug-abuse prevention animated special Cartoon All-Stars to the Rescue. With music by Alan Menken and lyrics by Howard Ashman, the song was written by the duo at the request of Roy E. Disney, producer of the special.
On his official website, Alan says of the song, "Back in the late 60's I would not have been the poster boy for this cause, but when we were asked to write 'Wonderful Ways to Say No' how could we say 'no'?"
Just say know. (Thanks, Jess Rotter!)
