Purgatory Flats

4 Wheels Down produced a song called "Another Drunk Phone Call" that appeared in the opening scene in the movie. Why was it not listed in the credits? This band has produced 5 of it's own records, with great music, and yet no mention is made in the credits. All of their albums, written and produced by Steve Easterling, have received great reviews, though not in the mainstream music scene yet. I thought that all music, regardless of the length in the movie, must be listed in the credits. It is a shame that 4 Wheels Down, or Easterling and Gildersleeve are not mentioned so that anyone that hears the music can find their own copy of the entire album, or at least a copy of the song.
