Showtime (Sun., Aug. 24, 8 p.m. ET)
Another withdrawal from the memory bank: Motown on Showtime, a six-part series, begins with a tribute to the Temps and Tops, as host Stevie Wonder calls them. You see and hear both groups now—including the Tops’ vocal jam session with Aretha Franklin. But mostly you see the groups’ glory days in a fine collection of old clips. In those clips, nobody looks or sounds older. That makes nostalgia easier to swallow.
