Jabberwock?

This is from an old television musical version of Alice Through the Looking Glass made back in 1966.  Palance was the villain of the piece as the Jabberwock.  Ricardo Montalban and Robert Coote were the  White and Red Kings.  Agnes Moorehead and Nanette Fabray were  the two queens.  Jimmy  Durante played "Humpty Dumpty".  It was not a good version, and had forgettable tunes, like "There are two sides to everything" (remember, when "Through the Looking Glass" begins, Alice walks through a mirror, and sees everything "backward" - however in the musical when she presents this as a philosophy to Palance, he shows to her that he is only one way: evil.  She runs off screaming from him.).  Durante keeps singing a song "Beware, beware the Jabberwock, my son."  Alice keeps reminding him she's not his son, and he sternly replies, "Be quiet, I've just  begun!"  At the end of his song  he sings out "Here I go!!" and falls off the wall. The Smothers Brothers were "Tweedledum" and "Tweedledee".  British musical star, Roy Castle, was given the role of "Lester the Jester" (a character never thought up by Lewis Carroll).   At the end of the show Alice has managed to put enough courage into the other characters to make them confront and destroy Palance's Jabberwock.  But Alice  is no longer around.  I can't recall who played Alice - she was hideously bad, although so was the confused script and tunes.
