The Rent Party episode
This was a significant episode in many ways:
James's (John Amos) last appearance
J.J. (Jimmie Walker) does not appear
First of the "put on show" episodes
Also, Michael (Ralph Carter) gets a chance to show his singing talent, while Bookman (Johnny Brown) shows his gift for impressions. We see Willona (Ja'net Dubois), Thelma (BernNadette Stanis) and Florida (Esther Rolle) attempt their version of The Supremes, though Thelma and Florida clearly are no singers.
Still it manages to be an entertaining episode, Ralph Carter's singing is very good, and Esther Rolle and John Amos's reactions to it are touching and funny. Johnny Brown is entertaining with his impressions of Ed Sullivan, Wolfman Jack, Howard Cosell and Muhammad Ali.
