I am already thinking about the keyboard parts..
A wurlitizer patch for comping
and a B3 for the pads, heck I may load the stems onto a laptop and bring it to to my studio where my 1930s A/V and Leslie 147 reside miking it up, of course, and record the organ tracks with it
otherwise my Hammond SK2 and motion sound , I am already running parts thru in my head
