Ellington's appearance at the Newport Jazz Festival on July 7, 1956 returned him to wider prominence and introduced him to a new generation of fans. The feature "Diminuendo and Crescendo in Blue" comprised two tunes that had been in the band's book since 1937 but largely forgotten until Ellington, who had abruptly ended the band's scheduled set because of the late arrival of four key players, called the two tunes as the time was approaching midnight. Announcing that the two pieces would be separated by an interlude played by tenor saxophonist Paul Gonsalves, Ellington proceeded to lead the band through the two pieces, with Gonsalves' 27-chorus marathon solo whipping the crowd into a frenzy, leading the Maestro to play way beyond the curfew time despite urgent pleas from festival organizer George Wein to bring the program to an end.
