Carmelina is a musical with a book by Joseph Stein and Alan Jay Lerner, lyrics by Lerner, and music by Burton Lane. Based on the 1968 film Buona Sera, Mrs. Campbell (which also inspired the book for Mamma Mia!), it focuses on an Italian woman who has raised her teenaged daughter Gia to believe her father was an American who died heroically in World War II. Supposedly she spurns the constant advances of local café owner Vittorio because her heart still belongs to the man she tragically lost. In reality, she had affairs with three different GIs and has no idea who fathered the girl. Trouble ensues when the three veterans decide to reunite in Carmelina's small hometown.
