An amazing guy. He's definitely alive, successfully battling pancreatitis, has lost a vast amount of weight since the filming of "Genghis Blues" and is still gigging and doing his unbelievable "kungaraa" (sp?) or "Earthquake-style" throat singing. Good on ya, Paul; may you keep on rattling the vault of heaven for years to come!
Toward the end of his life, Frank Zappa became very interested in Tuvan Throat Singing as well; you can find some bits and pieces about his fascination with it on the official Frank website, here: http://www.zappa.com
