Violent Femmes "Intro": what's the story?

The “intro” track on the Violent Femmes’ “Add it Up” album appears to be some kind of rant directed toward the audience at a concert.

Is there a story behind it? What preceded/inspired the rant?

If I remember right this was from their concert at the Oriental theatre in the 80s.
(One of their albums has the original radio ad for this concert)
I had a chance to go but was not as big a fan at the time as my friends were. They all went and in hindsight I wish I had.
I believe the guy was just introducing the band and was trying to pump up the audience.

Oh, thank goodness. I was afraid the rant might have been about me.

I fell asleep in front of the stage during one of their shows at Century Hall. I’m sure they were totally impressed with me.

hey, I’d been up for 24 hours. I’m sorry!

Huh, I’ve never ever thought that to be a “rant.” I just thought it was some concert venue guy introducing the band in a funny way, and they liked it so much they used it as the intro to their compilation album.
