Meet Cathy, who's lived most everywhere, From Zanzibar to Barclay Square. But Patty's only seen the sights A girl can see from Brooklyn Heights - What a crazy pair! But they're cousins, Identical cousins all the way. One pair of matching bookends, Different as night and day. Where Cathy adores a minuet, The Ballet Russes, and crepe suzette, Our Patty loves to rock and roll, A hot dog makes her lose control - What a wild duet! Still, they're cousins, Identical cousins and you'll find, They laugh alike, they walk alike, At times they even talk alike - You can lose your mind, When cousins are two of a kind. source: The Patty Duke Show Lyrics - Theme Song Lyrics
I read her biography years ago. Since then, I admired her and she gave me the courage to deal with my own issues. Great woman!!
