You can always Shazam it while the movie’s playing to see what that brings up.

I’ve attempted that and sadly it doesn’t know

Are you watching the 110-minute original cut or the 96-minute director's cut (the Criteiron version)? On the Criterion version, I don't hear a new song starting at 29:44, it's just the same song that has been playing since 28:30, which is "Okie Dokie Shuffle" by Dr. Loco & Sus Tiburones Del Norte.

This was in the 110 minute directors cut not my Criterion copy.
