"It Can't Be Wrong" was written by Dick Haymes, one of the most popular American male vocalists of the 1940s and early 1950s. He wrote the song in 1943 and it became a minor hit during the first months of the Allied invasion in the Second World War. It is adapted from the Academy Award-winning theme which Max Steiner wrote for the 1942 Bette Davis film Now, Voyager (which featured Trek guest actor Ian Wolfe). Steiner reused it in the theme of the 1945 film Mildred Pierce, which was directed by Michael Curtiz, stepfather of TOS writer/director/producer John Meredyth Lucas and photographed by Ernest Haller. According to M. Evans – author of Soundtrack: Music of the Movies (Da Capo 1979) – and other sources, the Max Steiner theme from the 1942 film Now, Voyager had lyrics written by Kim Gannon.
Wrong Would it wrong to kiss Seeing I feel like this Would it be wrong to try? Wrong Would it be wrong to stay Here in your arms this way Under the starry sky If it is wrong Then why were you sent to me Why am I content to be With you forever? So When I need you so much And I have waited so long It must be right It can't be wrong
