The local WHDH-TV Boston production of "Bozo's Circus", with Frank Avruch playing Bozo, aired daily from 1959 until 1970. In 1965, Larry Harmon became the sole owner of the Bozo licensing rights after buying out his business partners, and produced 130 episodes of the Boston-based Bozo show between 1965 and 1967 and syndicated them to local U.S. television markets that did not produce their own Bozo shows. The half-hour syndicated shows were retitled "Bozo The Clown" (on episodes with a 1965 date) and "Bozo's Big Top" (on episodes with a 1966 date). Caroll Spinney (billed in the credits as Ed Spinney) appeared as various characters which included Mr. Lion and Kookie the Boxing Kangaroo. He later went on to portray Big Bird and Oscar the Grouch on "Sesame Street". Carl Carlsson also appeared as Bozo's sidekick Professor Tweedy Foofer. Ruth Carlsson also appeared in several 1966 episodes. Harmon supervised the taping of these episodes, with Harmon-approved characters added, some based on characters in Harmon's classic 1958–1962 animated "Bozo" cartoon shorts which also aired in each episode. These were the only Bozo shows Harmon fully owned. Bozo's frequent exclamations on the show included, "Whoa, Nellie!" and "Wowie Kazowie!" and always ended the show with, "Always keep laughing!"
