Hank may have faded into oblivion due to medical and other issues but he didn't die young the way Morgan or even Green did. He was 56 when he died in 1986. Too soon, but not 'young'.
I've been on a Mobley kick the past several weeks during my commuting, earlier in the year I listened to all of the 50s material and now most recently it was the 60s leader dates. Still don't have much use for Reach Out but if you've only heard one leader date I would go straight to Soul Station, Workout, Roll Call, No Room For Squares, and then all the rest for good measure.
