Neil Young tops my list too(that was a terrrific rant catspaw), but in a solid second place is Van Morrison. He cant sing, he can't compose,he can't play an instrument to speak of,and his blackface minstrel vocal inflections although very nasal, or at least always out of tune. And his "musical career" has been going strong for over 30 years!! He makes James Taylor seem a musical genius by comparison.
