Anyone notice that Apple calls some their commercials "films" and some ads? Goes to show that they don't want people thinking that some of their advertising efforts are anything like what companies normally produce.
What can I say? Written by George Gershwin, lyrics by Ira Gershwin. The last song George wrote before he died. A classic. A main theme in the 1951 Gene Kelly movie An American In Paris, which of course, included Gershwin's An American In Paris symphony, and the incredible choreography by Kelly.
Sung by many, an Ella Fitzgerald classic with Louis Armstrong.
I'd say you need some heavy re-educat'n.
