MODERN FAMILY
ABC, 9:00 p.m. ET
This series’ executive producers include Christopher Lloyd (the writer-producer, not the actor) and Steven Levitan, both of whom did brilliant work crafting Frasier, starring Kelsey Grammer in his impeccable Cheers spinoff. Tonight, Modern Family makes room for Grammer as a special guest star, playing an old boyfriend of Cam’s – a former circus ringmaster and now concierge.
