I, too, never understood why the Tonys didn't bump Mullally up, so she'd be the third nominee for Leading Actress in a Musical.
And Elaine Stritch (''Show Boat'') could've been the 4th nominee; she was billed above the title and didn't want to be in Featured.
Stritch: ''When I have billing on the same line with Cap’n Andy [John McMartin], I want to be nominated for leading lady. I don’t give a (bleep) how many lines I have or how many songs I have. I don’t want to be up for support. Not that I have anything against supporting players — the name itself is my idea of theatre — but, very much like 'Company,' everybody in 'Show Boat' is an ensemble player. There is no star in 'Show Boat.'”
