One of the neat things about seeing Tori Amos live are the improvisational parts. And, they can be especially amusing when they come out of flubbed songs. Here’s a performance of Professional Widow I found on youtube with a new “Things F*ck Up Sometimes” middle section 
Most bands I’ve seen, when they mess up, just keep going and finish the song. I don’t think I’ve ever seen a band that mess up so badly they couldn’t finish the song. But, Tori seems averse to just playing through errors. She usually stops and calls herself on it. It’s funny and the fans love it.
