Rare Treats: The original open to the Scooby-Doo/Dynomutt Hour (1976)

 Oh, man, this is a treat.

You've seen the individual opens for Scooby-Doo & Dynomutt dating back to 1976, but those were actually meant for syndication, it seems.

Following is a video that plays the audio of the original Hoyt Curtin composition, with Don Messick, Frank Welker, & Casey Kasem aiding the "Hanna-Barbera Singers" of the period. Gary Owens (Blue Falcon) is only heard introducing the show, leading to the theme.

Just for fun, SufferingFoolsMusic, whose channel provided the above clip, also unearthed the audio theme from The Think Pink Panther Laugh & a Half Hour & a Half Show, also from 1976, mixed with some choice clips of the Panther, plus The Inspector, Misterjaw, & Texas (Tijuana) Toads. Keep an eye open for Crazylegs Crane, who'd get his own feature when the Panther left for ABC 2 years later.
