Hudson Brothers Show, The
No sooner was The Sonny & Cher Comedy Hour a hit than its producers, Allan Blye and Chris Bearde, sought to replicate that success on Saturday morn with an act called The Hudson Brothers. Promoting Bill, Brett and Mark Hudson as the seventies version of Groucho, Harpo and Chico, CBS launched them as the summer replacement for Sonny and Cher, with a show that aired in primetime from 7/31/74 to 8/28/74. This segued into the half-hour Saturday AM version, which was called The Hudson Brothers Razzle Dazzle Show. That one lasted one year, commencing 8/7/74.
Both shows featured zany sketches and music (the Brothers had some modest record hits around then) and a family of regulars that included Gary Owens and Rod Hull. Rod Hull was an Australian comedian who worked with a large bird puppet called Emu. You can read all about Rod here.
Oddly enough, the primetime version — which had only been intended to launch the brothers in preparation for their Saturday morn show — probably fared better. There was talk of later bringing it or them back in some format but the act instead drifted through other venues and the Hudsons went their separate ways.
