Butch Cassidy and the Sundance Kids (1973)

From Wiki- Similar to both Scooby-Doo, Where Are You! and Josie and the Pussycats on CBS, the show depicts the adventures of the titular teen pop group.^[3] The band consists of 4 heartthrobs: Butch Cassidy (lead vocals and lead guitar); mini-skirted blonde beauty Merilee (tambourine); sensible Stephanie, nicknamed Steffy (bass guitar); and curly-haired Wally (drums). Accompanied by Wally's dog Elvis, these popular rock stars lead double lives as government-backed crime-fighters.^[4]  The teens are advised by a supercomputer named Mr. Socrates, who is (somehow) violently allergic to dogs. When the group meets with Mr. Socrates in his lair for their latest assignment, Elvis is always told to stay outside. Yet Elvis always ends up inside the lair, by his own ingenuity and/or by Wally's forgetfulness. Elvis's mere presence causes Mr. Socrates to sneeze and go haywire; Mr. Socrates then sends the group out of the lair, and off to their assignment. Butch, designated as "Sundance 1", wears a special communicator-ring which keeps him in contact with Mr. Socrates.  Back to me:

I vaguely remember this series when it was on TV, but it sure lost out to Land of the Lost back then.  It was even on NBC.  Go figure.  It is pretty much a cross between Scooby and Josie, with secret agents thrown in.  The first episode was fun, too bad they had to include the canned laughter.
