A few years ago I had been asked if my MIDI rendition of Edvard Grieg's "In the Hall of the Mountain King" could be used in a Short Film - and I granted a license. The film was "The Spooky House", by Dennis Miller (Monkey Ltd Films).

My MIDI rendition is from 2:43 until 5:02. This is my first (and so far only) time that my music had been used in a film.
