That's what I figured as well. It's not a huge big sequence that was deleted, just a small fraction of a song... and quite possibly the best part of that song. I still don't get why extending a song so it sounds good would ruin the flow. I still don't understand the deletion of the MTI sequence in Cabin Fever with "We were sailing, SAILING, over the bounding main.... and now we're not."Maybe I'm wrong, but somehow I doubt this scene had any dialogue in it. On the soundtrack, the flashback is told strictly from Tex's point of view, with no real break for dialogue. I want to say that the scene was shown silent, with the 'operatic' portion of Tex's rap song playing over the footage. I guess we'll just have to wait and see.
P.S: Good detective skills, muppetlover!
