I am so excited! I can’t believe that my question has been answered after 30 years! It wasn’t “Kaptain Kool and the Kongs” (a very good guess by the way… and what actually sent me to the site that finally ended the search for my silly holy grail) it was another Sid and marty Kroft show called “The kids from C.A.P.E.R.” Here’s a link: More Kids from C.A.P.E.R. Photos.
If that worked and you want to check it out there are even pictures and yes there was a hottie in the blue velvet suit! He wasn’t some teenage hormone induced memory. Man, I can’t believe it Thanks!
Thank you Frank! Glad to be here! 
Ha! you make me laugh!
Uh-oh, Chango!
Thread devolves into a 1970s era teener heart throb discussion?
Well, guess what I saw sometime last week, or at least parts of it? Corvette Summer! Remember when Marky-Luke was being touted as the next best thing for teenage girly lust since zuccini? Yeah, he was actually a cute boy (even this hetero has to say) back then. And I loved the 70s era bikini bimbo blondes in it, too. Pity about that ice monster.
Corvette Summer had boys in it?
I only remember the very young and very cute Annie Potts. 
Oh, Danny Partridge was in it I think. Did he count as a boy?
