Who knew?!
Okay, obviously at some point, quite a few people knew that Frank Sinatra’s 1955 hit song, “Love and Marriage” (commonly recognized as the theme song for “Married… with Children”) was originally composed for and featured in a 1955 television musical production of the Thornton Wilder play, “Our Town.” The episode of “Producers Showcase” starred Frank Sinatra as the Stage Manager, as well as Paul Newman and Eva Marie Saint. I myself had no idea until I happened upon this vintage sheet music at a library sale.
This 2016 NPR piece revisits a few choice moments from the television production and includes snippets of Paul Newman and Eva Marie Saint singing, as well as a sound clip of Sinatra performing “Love and Marriage” for the first time.
