"Source Information for The Usher's Tapes Tree

"the person who is responsible for the bulk of the capitol theatre audience recordings is a fellow by the name of ken lee (not sure of his last name spelling). this is the
guy who was employed by howard stein (local ny area promoter of the time) my source is his brother in law, mark c (a long time dead head & quite a nice & unassuming person) i owe mark a huge debt of gratitude. 

ken's port chester masters were recorded on a sony cassette deck (don't have the 'model # or mic info) his positioning was generally center lodge with mic's mounted on the rail. 3/21/70 had the mic's spaced at over 15 feet, and the recording bears out that information.
