Every once in a while on Captain Kangaroo, there was a musical skit. One was a Japanese folk song - Sho Sho Shojoji (title?) that had little cartoon characters bowing at each other. Another skit had to do with a kid named Little Willie and how he wanted to be a member of the band. (I have really vague memories of it being Mr. Greenjeans dressed up in a sailor suit uniform)

Any way, Little Willie tried various instruments and found them not to his liking. Again vague memories - the trumpet was too hard to play? Little Willie eventually found out that his forte was to be the band leader.

Why am I bringing this up?

Because I have the dratted song stuck in my head...

Little Willie, Little Willie, he's the leader of the band...

Can't remember the rest of the song, just have that one line and the tune of the next line stuck in my head on endless repeat.
