I have a friend who is a studio musician in Toronto. He played keyboards and Hammond Organ on one of Gordon's records. Apparently, Gordon was very meticulous about instruments being in tune. He was known to tune a piano if he felt it was out. He would do multiple takes of each song, and keep the tape of all the takes. Even if he felt a take of a song was perfect, he would say, "Great job boys. That was perfect. Let's do it again".
