[HAM] What's the most distinctive clue? BF Test #7

[OF]

Johnny "Hammond" Smith's soloing is distinctive to my ear, but the dead 
giveaway for me, the one I mentioned earlier, is that when he comps chords, 
he often surrounds the chord with an octave. Say it's a Gm7th. He might 
play it as Bb, D, F, Bb. None of the other famous jazz organ players ever 
do it AFAIK, but it was more commonly heard in the old-style organ music. A 
beautiful, juicy effect.
