John Paragon was also a cast member, although he doesn't yet appear in the IMDb cast list.
A favorite segment was "Soul Truck", a ripoff of "Soul Train", a blackout segment framed with the ridiculous image of the entire cast, in costume, rolling along, dancing, in the back of an open-topped flatbed truck, with the signature line, over music, just as delivered in the Don Cornelius program: "Soooooooooouuuuuuuuul Truck!".
The show was syndicated, which accounts for the show's being seen all over the schedule.
I'm guessing some of these folks are Second City alumni. The series is a great example of some very clever, very funny work by folks, some of which (in the case of Frank Welker) who have been doing much creative work off-camera or, in the case of Howie Mandel and Gail Matthius, on other established programs.
Wish this one was on DVD! Very funny without being offensive.
