Dweezil Zappa joined Jimmy Kimmel‘s band Cleo and the Cleotones last night at the Hollywood television studio set of Jimmy Kimmel Live. Without ever fully engaging in a complete song, Dweezil helps the house band rock in and out of show breaks with covers of AC/DC‘s “Black In Back,” the Allman Brothers Band‘s “Whipping Post,” and Frank Zappa‘s “Willie The Pimp.” Special guests of the show include Will Arnett and Gabrielle Union!

Watch clips of his late night jamming below:

Fans of Frank Zappa might remember his mind-blowing cover of “Whipping Post” from the early 1980’s. Watch it here if you haven’t already!
