There's a wonderful section in the second volume of Kaplan's massive biography where Sinatra has hired Johnny Mandel to arrange the first album for Reprise, and Mandel describes working with Sinatra in the studio. In particular, he remembers with crystal clarity that Sinatra could listen to a complex arrangement once and know exactly what he was going to do with it, making detailed suggestions--well, orders--so it would be perfect. Pp. 358-362, if anyone is interested. I guess I'll get this one at some point. I have everything else.....
