Just found this interesting article. Not a bunch of training stuff but still interesting.

"Once, after an all-night party in Frankfurt, when a policeman refused to allow him and Moore to catnap on an airport bench, they went outside and located a plot of grass. Shorter took off his shirt, pulled his pajama top out of his suitcase, put it on, set his alarm clock down next to him on the grass, and he and Moore went to sleep for a few hours. When the alarm sounded, Shorter got up, took off his pajama top, put on his shirt, and he and Moore went to catch the plane."
