Vol 1 of the Tatum Group Masterpieces features Benny Carter, Alto Sax, Louis Bellson, drums, and Art Tatum, Piano. Undecided was written by Sid Robin and Charlie Shavers and published in 1938. Early recordings of Undecided were made by John Kirby and Ella Fitzgerald. Ella Fitzgerald’s version is my favorite vocal version.
