The evening began inauspiciously. Some of Ellington's band members showed up late. The earlier numbers in his set were met with tepid, if pleasant, applause. As Ellington announced the next numbers, Diminuendo and Crescendo in Blue and the soloist, tenor man Paul Gonsalves, there was no indication that something very special would happen within the next 10 minutes. The band made its way through the Diminuendo section in about 4 minutes when Gonsalves approached the mic and IT happened.
