One of the most interesting things about this tune is the offset syncopated bass line, which works against the strict 3/4 time of the tune. Unfortunately, iReal Pro has no way to replicate this bass line, as it cannot subdivide the bar into eighth beats.

Played by the Fred Hersch Trio.

The tune is on pp 303-304 of Sher's New Real Book, Volume Two.
