I just heard that Jon Lord, keyboard player for Deep Purple, died two days ago of a pulmonary embolism.
So for tonight's Zappa post, I present, of course, Deep Purple's most famous song -- about a Zappa concert.
It's an appropriate video -- not only does Lord introduce it, but, while the song's best known for the guitar part, this version has a solid keyboard solo.
(Also appropriate: the fire started during a keyboard solo, too.)
