Mg123, the back cover will have a copyright-type logo toward the bottom which will show the date of the recording. Was the 77 recording analog or digital, anyone aware? I have the '63 recording both on CD and vinyl, and it's an excellent performance. I'm intrigued by the Celibidache recommended by Iasi, as Iasi played the scherzo movement of that version for me and it is a MUCH slower tempo than anyone else's I've heard (advantage of cleaner and more precise articulation of the strings, disadvantage of less energy in the movement), and the version is over 75 minutes long in total! It's a live recording and well recorded by EMI; probably worth considering as an alternative to other, more conventional versions.
