"The Trolley Song" is a song written by Hugh Martin and Ralph Blane and made famous by Judy Garland in the 1944 film Meet Me in St. Louis. In a 1989 NPR interview, Blane said the song was inspired by a picture of a trolleycar in a turn-of-the-century newspaper. In 1974, he had said the picture was in a book he had found at the Beverly Hills Public Library and was captioned "'Clang, Clang, Clang,' Went the Trolley."
