This is Ella Fitzgerald's somewhat sultry and brooding version of Caravan from her 1957 "Duke Ellington Songbook" album. Tonally quite advanced for its time, the chart moves from a quasi-samba feel to a double-time swing and back to half-time samba for the close. There is solo space for Clarinet (scored on the Alto 1 part) too. This chart needs a good singer who can pitch and maintain what is quite a tricky line, as much of the double time section is scored for singer and rhythm section only. The cameo Trumpet and Clarinet solos are written out "as played" and, aside from Alto 1 on Clarinet, there are no sax doubles.
