[progdirjim(Admin)]

the common thread was Zappa guitarists:

Crossroads - Steve Vai played Jack whoever (the devil's guitarist) in the movie Crossroads (and he kicked Ralph Macchio's punk ass in the contest, despite the Bach bullshit!)

Duran Duran - Warren Cucurullo played guitar for both Zappa and later a reformed Duran Duran

Dolphins - Mike Keneally's band for some time was called Beer For Dolphins....
