The Caroline question...one that has long plagued me as well.
I thought it was something like - "What if I don't want to..what if I don't want to cut my-y chord" - repeating the "cut the chord if you can" idea in the song. But I've never known anyone else who heard that, so I think I might be out there a bit.
Hmmm, I'll have to take another listen to Go Insane....never really noticed that one before.
