Music from the Wasteland (ZZ Top Velcro Fly)

I was reading The Wasteland (The third book of the Dark Tower series) by Stephen King not long ago. The party of gunslingers had entered the city of Ludd and began hearing music broadcast from speaker systems throughout the city. When the music started, the residents of the city went on a killing spree. They called the music "The God Drums". The music ended up being the drum track from the ZZ Top song Velcro Fly. I got curious and looked it up on youtube. Listening to the song, I could imagine how it could work people up into a killing frenzy.
Here's an interesting note: I saw all kinds of Dark Tower references in the comments section. On another link from the song that I clicked, people were saying that the Tower sent them. Made me laugh.

Anywho, here is the song, for your listening pleasure. Don't kill anybody.
