so sorry to hear of his passing. great teacher and author. his "stompin' at the savoy" (from concepts) was my opener for quite a long time. killer arrangement, although one of those put in 'guitar key'. see his last book for some tunes done both ways--a real education, this one:

Godspeed, maestro.
