The Mulligan the Arranger LP also included the great "All the Things You Are" referred to above by Larry Kart.
Taking of Mulligan the arranger, I was looking at the notes for the RVG of the "Birth of the Cool" sessions and realised that Mulligan wrote 3 number (more that anyone else), arranged 6 (more that anyone else) and played on all 12 of the tunes (more that anyone else, except Miles, I think), although in the notes he wrote for one of the early re-issues of the material he gives Miles full credit for "creating" the "Group", I can't help but feel that it's almost as much a Mulligan record as it is Miles's.
Some good early Jeru on this one;
In this Jazzwax interview, in answer to the question, "Was "Deception" truly arranged by Davis? It sounds a lot like Mulligan", Gunther Schuller replies: "Look, Miles immediately learned from Gil and Gerry. In those days, very often, some other person's name was put on the ttle for one reason or another."
