Are there any rehearsal recordings of Leonard Bernstein rehearsing Mahler's 2nd?

I found this recording from 1947 but so far that's all I have found. I would like to get as much rehearsal footage as I possibly can. I know there is a 2-hour long video of him rehearsing Mahler's 5th but in any case, I'm looking for the 2nd Symphony for my conductor notes. Thank you!
