No one has mentioned my favorite, the Toscanini recording with the NYPSO in a recording from 1936. In my opinion, and a few others, the first 4 minutes of the first movement as originally approved by Toscanini are preferable to the faster substitution made for later RCA pressings and RCA has continued with the substitution for ever. Pearl issued a nice set of Victor's Toscanini / NYPSO recordings a few years ago with the original side and regrettably I can't locate my copy at the moment.
Bev must be going nuts searching for the Pearl issue.
