These are so hilarious! Amateur pianist Hiroki Niwa, a huge Gershwin and Confrey fan, has used a Japanese singing synthesizer program, Miku Hatsune, to make it sing some Gershwin songs. It only can sing in the traditional Japanese syllabary, so it can't render sounds like V, F, or "tee" sounds etc., but he does a pretty good job of faking it.
