Thanks for your feedback: "I think The Royal Guardsmen should be on your one hit wonder list.  I think they had a hit with Snoop Vs. The Red Baron, but I don't think the sequels were that popular. The sequels were Return Of The Red Baron, and Snoopy's Christmas. They were on the Laurie record label. "

Good try - but they are not a one hit wonder.  "Snoopy vs. the Red Baron" reached #2 on the charts in 1967.  The follow up single, "Return of the Red Baron" actually made it to number #15 on the charts, thus making the band more than a one hit wonder.  In 1968, the band had it's only non-novelty hit, "Baby, Let's Wait" which never made it past #35.

Great suggestion though!
