Here's a MIGHTY WEIRD reference to Muhammad Ali:
Ali and His Gang vs. Mr. Tooth Decay
"Start with Muhammad Ali spending 40 minutes discussing tooth decay. Add appearances by celebrity guest stars like Frank Sinatra and Richie Havens, a bunch of kids, and some truly wooden dialog straight out of a dental textbook. Throw in a song that doesn't make any sense. And if that isn't enough for you, top it off with narration by Howard Cosell."


I see a reference in SING OUT! here:

to a song: Muhammad Ali by Greg Trooper (© 2003 Songs of Welk / BMI. Admin. by Yak Yak Music. but no lyrics.
