With a new chord every two beats, the A sections become an almost continuous chain of ii-Vs, which is why the form is a test piece at jam sessions, usually fast and in Bb. Rhythm sections mix these changes with the original ones freely. Practice the A section in two-bar pieces, and the bridge as four ii-Vs falling in fifths.
