Alan Livingston was the president of Capital Records and created Bozo who was voiced on the first read-along record in 1946 by Pinto Colvig. In 1949 Bozo appeared on KTTV, Channel 11 in Los Angeles and I was watching. Pinto made more read-along record albums. I have several of them. Pinto played Bozo until 1956 or so. If Pinto's voice sounded familiar, it was because he was also the voice of Disney's Goofy. I knew his son, Vance Colvig, who played Nutsy the Clown, on his own early TV show in LA. Vance was a lovely guy and a fine character actor in his own right. Vance (or more accurately Vance Colvig Jr) also played Bozo on LA TV from 1959 to around 1964, working for Larry Harmon who owned the rights by then.
When Capital Records got out of children's entertainment, they sold the rights to Larry Harmon who was a master marketer. Unfortunately, Larry also took as much credit as he could for creating Bozo, ignorning Livingston and Pinto's participation. He would later claim that he'd been "mis-quoted." It was baloney. He just took the credit until he was called out.
I knew Harmon because he owned the rights to the images of Laurel and Hardy. I brokered a deal with him so my wife (a portrait artist) could do a collector plate of the two comedians. Bozo (and L&H) had made Harmon wealthy. He lived in a condo on Wilshire Blvd in a wealthy section of Los Angeles in a high rise. His condo was the entire floor. It had to be that large to contain his ego.
