In honor of what would have been Gene Kelly's 100th birthday, we found this rescored excerpt from Vincente Minnelli's 1951 film starring Kelly and newcomer Leslie Caron. The movie featured the Gershwin songbook to the letter, at Ira Gershwin's request, but the ballet interlude scoring was left to musical director Saul Chaplin, who "reorchestrated, rearranged, and edited" George Gershwin's original music. Chaplin wasn't happy about remixing the master, but nevertheless went on to win an Oscar for his efforts. This Vimeo user sets the excerpt to a New York Philarmonic recording of "An American in Paris" to see how things sync up, gaps and all.
