The musical quote during 2001 is Michael Jackson's "Smooth Criminal." @whatstheuse324 said:

Great review, @multibeast. I was able to stay up and watch the show in its entirety from the east coast until 2:50 AM. I would have to give this one the nod for the show of the year so far.

The musical quote you mentioned being played in 2001, although I do not know its origin, was definitely present in my favorite version of the song, 10/9/1999 in Albany. In the middle of this super-extended version, the band drops out while Mike lays down the same "quote" with his baseline. Check it out if you are so inclined.

Also, the comedy routine at set break was excellent. It was delivered, via text, with the same spot on sarcastic style as Steven Wright. What a treat!

Can't wait for the rest of the west coast shows...
