Song titles are usually short, memorable, something of the song’s essence in a short phrase. But not always. Some song titles go on and on and on. Some bulk up their titles by adding phrases in brackets.
Hoagy Carmichael may hold the record with a 30 word song title, The Faces have one with 28 words. Honourable mentions to Panic at the Disco, Brian Hyland, Pink Floyd, Lana Del Ray. The longest title I could find is by Christine Lavin, with 97 words.
It’s a small but significant, and really entertaining, musical sub-genre.
