The KNKX studio session opens with Harold Arlen's cheerful standard at 123 BPM, performed as a voice-and-piano duo. Calderazzo takes a one-chorus piano solo over the 32-bar AABA form, followed by Elling's half-chorus vocal improvisation. The contained solo lengths suit the intimate duo format, where every note is exposed without a rhythm section to fill in behind. Arlen composed the piece in 1933 with lyrics by Yip Harburg and Billy Rose, and it became a standard through recordings by Ella Fitzgerald, Nat King Cole, and others. The four-minute performance sets a warm, conversational tone for the three-tune session, with the familiar melody providing an accessible entry point before the duo moves to more introspective material. The swing feel and medium tempo establish common ground between Elling's vocal style and Calderazzo's pianistic approach, setting up the contrasting ballad that follows.
