Girl Crazy is a 1930 musical by George Gershwin with lyrics by Ira Gershwin and book by Guy Bolton and John McGowan. Ethel Merman made her stage debut in the first production and co-lead Ginger Rogers became an overnight star. Rich in song, it follows the story of Danny Churchill who has been sent to fictional Custerville, Arizona, to manage his family's ranch. His father wants him there to focus on matters more serious than alcohol and women but Danny turns the place into a dude ranch, importing showgirls from Broadway and hiring Kate Forthergill as entertainer. Visitors come from both coasts and Danny falls in love with the local postmistress, Molly Gray.
