Agreed that the 1982 Lanchbery recording is lovely, and I'd add, better recorded in a large hall than the up-close version on the Choreography by Balanchine video, which is very clear for all that. Lanchbery's tempos are easier in the adagio than Robert Irving's, and I think he makes a slight cut or omits a short repeat Irving plays in the coda -- I can't nail it exactly without a score to follow -- so his running times are about a quarter-minute longer in the adagio but a half-minute shorter in the coda.
Here's that link:

I'll bet
rg is right, but I can't find the thread. BT's search function won't accept three-letter words, and gives me 2000 hits; Google seems not to be allowed to search this site.
