The Frogman:
They, Smith & Getz, seemed to be focused on playing 'moonlight in vermont'. Almost, but not quite, note for note as a singer might sing it.
I think Person and Defrancesco just used it as a good place to start.
Although Person went further away from the melody as the tune progressed, I never forgot they were playing 'Moonlight in Vermont'. To me, this is the genius of Jazz. Besides, Defrancesco was there.
On his Cd 'Boppin' at the Bluenote', Jon Hendricks does the Lerner & Loewe tune 'Get Me To The Church On Time', from My Fair Lady.
When he finished he said, "I bet THEY didn't know THEY wrote THAT!! The THEY being, Lerner & Loewe. The THAT being his 'take' on 'church on time'.
Cheers
BTW, there are much worst places to be musically, than a Baptist church. Some good stuff there.
