According to the ASCAP (American Society of Composers, Authors and Publishers), in addition to the song ‘
So Long And Thanks For All The Fish’, composed by
Joby Talbot &
Christopher Austin and written with Garth Jennings, for the film
The Hitchhiker’s Guide To The Galaxy, Neil Hannon is also credited as the writer and composer for a song called ‘Thanks For All The Fish’.
While it could be a mistake in their listing – Neil Hannon actually only sings the reprise of
Joby Talbot’s song – it could also be as well a different song composed for the film which was actually not retained.
