Watched an old documentary last night (on video) on Lenny Bernstein ('Reaching for the Note'

and was moved by his fortitude in his final months.
I then made a mental note to try and obtain (or, at the very least, hear) his final concert from Tanglewood (19.8.90) with Beethoven 7 and Britten's 4 Sea Interludes and his Berlin Wall version of Beethoven 9 (Ode an die Freiheit) from 1989.
2 questions then arise: a) Is his valedictory Beethoven 7 treasurable? I know it cannot ever be a library recommendation, but I would love to hear it (DG have axed it, but I hear it may be making a re-appearance in a double CD set - any ideas?). Is the slow movement as sublime as I am led to believe?
b)What do the group think of his sweat-soaked and brick dust-caked Beethoven 9?
I agree that these are, in emotional terms alone, unique and that there are oodles of alternative - and possibly preferable - versions, but do they speak loudly of their moment in time?
Thanks.
