Oh, and the two Dannys, Whitten and Gatton. Another couple of guitarists I will miss hearing new music from is Bill Pitcock IV of The Dwight Twilley Band and Paul Skelton (a Telecaster master) of The Cornell Hurd Band (Austin, Texas). Both were heavy smokers, and paid the price. Lastly, Danny Gatton's sometimes-2nd guitarist/singer/songwriting partner, the madman Evan Johns. His vice was alcohol.
All the above were unable to say "Don't smoke, don't drink." Neither could everyone's favorite hard-rockin' singer, Bon Scott of the true Rock 'n' Roll band AC/DC, one of the few "screamers" I myself like.
