Emma Thompson guest stars as Nanny Gee, a popular children's singer whose sappy compositions make Barney the Dinosaur's ballads sound like Cole Porter. When Lilith (Bebe Neuwirth) suggests that baby Frederick might enjoy Nanny's upcoming Boston concert, Frasier (Kelsey Grammer) is forced into a startling confession. It seems that, before the ebullient entertainer was Nanny Gee, she was his first wife. ~ Hal Erickson, Rovi
