So he improvised them.
To this day, no one knows precisely what Gershwin played that afternoon of Feb. 12, 1924, at New York's Aeolian Hall.
In some ways, then, it makes perfect sense that another improviser,
jazz pianist Herbie Hancock, is performing the piece with the Seattle
Symphony Orchestra. While Hancock has no intention of adding anything
new to this concert-hall favorite — in fact, Hancock performs it reading
from the score — in a phone interview last week, the 14-time Grammy
winner explained that he does "swing" parts of it. More on Hancock from the source: Reported by Paul de Barros Seattle Times jazz critic
