sentences:  When WGN-TV started "Bozo" in 1960, Sandburg was not involved with the show until after it went to an hour format as "Bozo's Circus" in 1961.He was approached by station management to write for the program - he already wrote material for a morning program, "Breakfast With Bugs Bunny", that evolved into "Ray Rayner and His Friends" - but refused, suggesting instead that he be hired to appear as a character on air, offering to write material for the show at no extra charge (union pay rates for on-air talent were higher than for writing).WGN agreed, and the character "Sandy the Tramp" was born.
