The song with the longest title is 'Im a Cranky Old Yank in a Clanky Old Tank on the Streets of Yokohama with my Honolulu Mama Doin Those Beat-o, Beat-o Flat-On-My-Seat-o, Hirohito Blues' written by Hoagy Carmichael in 1943. He later claimed the song title ended with "Yank" and the rest was a joke.
