 One element of the original concept that was carried over was the live-in health-care provider for Frasier's father.Grammer points out that very little of the Frasier Crane of "Cheers" carried over to "Frasier", as his family history was changed (though this was later adjusted); the setting, his job, and even the character himself changed from the "Cheers" predecessor, having to be more grounded as the central character of the show so the other supporting characters could be more eccentric.Martin Crane was based on creator Casey's father, who spent 34 years with the San Francisco Police Department.
