Does instrumental of Zappa's 'Valley Girl' exist?

[Mark from Albany]

After more than two decades, I'm still fascinated by the instrumental track on Zappa's \"Valley Girl.\" I swear I've never heard such an aggressive and explosive bass track. I've poked around record stores and search engines from time to time to see if an instrumental-only track was ever released, but I've found nuthin'. Anyone know if one exists?

Check out Zappa on Crossfire [1986]. It's all about words (and censorship)
