Harpo Marx on Spike Jones

dOoLeY sez, "Spike Jones, who the announcer says 'set music back 10,000 years' features a 67-year-old Harpo Marx. If you listen closely at 18.32 seconds, you can hear the lead singer, behind Harpo's harp, give a musical shout out to Boing Boing.

In 1954, years after the dissolution of the Marx Brothers, Harpo was still going strong with TV appearances. He never grew old."
