My Fair Lady is that rare musical by which all others are measured. The tale of a cockney flower girl transformed into an elegant lady features one of musical theatre’s greatest scores, including: “Wouldn’t It Be Loverly?,” “With a Little Bit of Luck,” “The Rain in Spain,” “I Could Have Danced All Night,” “On the Street Where You Live,” “Get Me to the Church on Time,” and “I’ve Grown Accustomed to Her Face.”
