Frank Zappa: "Excentrifugal Forz"

After seeing Frank Zappa's son Dweezil play as the opening act for Return To Forever last summer, I have begun to dig Zappa's stuff.  I need to delve into a ton more of it that exists.  But, here is the first, short and hilarious song by Zappa that I got into.  This is "Excentrifugal Forz" which was not in the set list for Dweezil's set opening for RTF however.  This track is from Zappa's record entitled "Apostrophe".
