Hi - the Internet Movie Data Base - IMDB says former Bangles member Susanna Hoffs sang "The Water Is Wide" in a movie called Red Roses and Petrol. Can't say I've ever hear of the movie, but "The Water Is Wide" is an old ballad that has been around forever. You'll find links to lyrics for various versions above. Check YouTube, and I'm sure you'll find other recordings of the song.
