(Notes: Roz and Frasier appear on The John Larroquette show via archive footage edited into a conversation.

The characters of Frasier and Lilith also appear on an episode of Wings called “Planes, Trains, and Visting Cranes”, but this was released before the premiere of Frasier so it is a Cheers crossover.)
