Perhaps the least star-studded panel the CBS version ever saw just ended on GSN: From Carter Country Guich Cook, BS, CNR, from What's Happening!! Mabel King, from Flying (or was it Flyin') High, Ken Olson, and MW.
Granted, the three newcomers were all working at the time--Gene noted that Mabel King was also in The Wiz with Nipsey Russell, and Gulch and Ken certainly tried their best--but it was weird to see that many unfamiliar faces, I suspect even watching in '78.
