Dancin' is a musical revue first produced in 1978, directed and choreographed by Bob Fosse, who won a Tony Award for the choreography. The show is a tribute to the art of dance, and the music is a collection of mostly American songs, many with a dance theme from a wide variety of styles, from operetta to jazz to classical to marches to pop. Or as the VO says in the commercials: "We got spins, leaps, jumps, cartwheels and other incredible body-gyrations that I'm not allowed to mention on television."
