This chart is recorded on Cat's A Bear's "Tito In Wonderland".
The B section serves as an intro and a coda, with the coda vamping on the B
section harmonic material. We kick the Ab on beat four of measure one of the A
section. After vamping on the B section, we end on an Abmaj7 on the ta of
four, after kicking all of the other es and tas of measure
four of the A7 chord.
The feel is a double-time latin / samba groove.
