Having seen "The Shout", I can confirm that "From The Undertow" is used in the film, but only as a chord progression used as a very minimal underscore for a number of scenes. Frankly, there was actually very little music used in the film at all! I believe the music from The Shout was essentially a demo of the intro to "Undertow" that Tony created but was ultimately unused then reworked for the "A Curious Feeling" album.
