It would include the 60's. I think I recorded with him over a period of about four years in the 60's, and most of the time, this is going to sound very strange, but thank God for Sonny Payne's marital problems, because when Sonny Payne his regular drummer couldn't come into New York because his wife would throw him in jail, Basie would call me up. And I used to say to Sonny, "geez, Sonny, you're my man but you know these marital problems are really groovin' me. " And he would say some proper epithet, you know, epithet or whatever you call it. Because we were good friends you know. And he couldn't, because she was ready to put him in the slammer for like ten years. So that's how come it worked out that I would record with Basie. He'd take the charts on the road.  They'd play them for three, you know, I don't know he said a month or two, then they'd come into town, call me up, and I would sight read them and we'd record them. So that's when your sight reading's got to be up to par because you want to sound like you know them. And well I've been reading so much for so many years I think I did develop that skill pretty good. And I think those records sound pretty good.
