This is the only production that his available to the best of my knowledge on DVD.
Pity it had to be made as a film rather than a stage production. In absence of any other worthwhile production, this should get accolades for just being there. No doubt, the singing and the music are excellent. But for that, I would have preferred an audio CD.
Having bought it though, I am quite happy with it and I guess most people will also feel the same.... till another one comes along; preferably a stage production in widescreen and HD. I think Gershwin deserves that...
