I'd like to second the recommendation of the Dorati/Detroit SO version on Decca/London. A fine, rousing performance in excellent sound. It's the one I listen to.
El Salon Mexico -- old edgy version
I was listening to Bernstein's version of his strong aquaintence, Copland. It made me remember a version, much older that I heard while driving on a snowy night, so I daren't write down the details, nor remember as I spun round curves. But listening now to Lenny, he had an affection, but his creditable execution still has more Lenny mannerism than that other biting, crazy version of a real place. The pacing, the leaner raw folk was truly great. Can anyone help?
