Right, this is quite an epic post, because there's a lot to list (and if some of the information doesn't quite tally up with my original identification of the first cut in the second movement, it's probably because I didn't have time to take care over my notes first time round!

).
Anyway, I've spent most of today poring over the score for Cuclin's 9th symphony, and I can report the full extent of the cuts made to the score as used in the recording posted on this forum. The timecodes I use refer to the single track of the complete symphony, I haven't split the recording down into separate tracks for each movement...
1st movement (pages 7 to 82 of the published score):1: at 4m26s, at six bars after figure 9 (on page 27), the recording jumps to figure 16 (page 42). This amounts to a cut of 57 bars.
2: at 9m29s, at figure 27 (page 65), it jumps to figure 30 (page 76). This amounts to a cut of 29 bars.
The complete movement runs to 340 bars, of which only 254 have been recorded. The duration of those 254 bars comes to 11m03s. Assuming the average tempo of the missing bars to be the same as those recorded, an approximate duration of the whole movement would be
14m48s.
2nd movement (pages 83 to 219):1: at 21m29s, at six bars before figure 21 (page 132), it jumps to eleven bars before figure 36 (page 175). This amounts to a cut of 276 bars (!).
2: at 22m49s, at figure 39 (page 184), it jumps to figure 49 (page 212). This amounts to a cut of 159 bars.
The complete movement runs to 965 bars, of which only 530 have been recorded. The duration of those 530 bars comes to 12m40s. Assuming the average tempo of the missing bars to be the same as those recorded, an approximate duration of the whole movement would be
23m04s.
3rd movement (pages 220 to 283):Now, this one gets a bit messy!
1: at 26m12s, at figure 2 (page 223) it jumps to figure 4 (page 225). This amounts to a cut of 40 bars.
2: at 27m57s, at three bars after figure 5 (page 226), it jumps to ten bars after figure 5 (page 226). This amounts to a cut of 7 bars (I dunno, they make a 276 bar cut in the 2nd movement and then a 7 bar cut here – weird!).
3: at 29m21s, at one bar before figure 6 (page 229), it jumps to.... Well, this is where it gets messy!At this point, there are only 54 seconds of the movement left on the recording, and yet somehow, we're only at the top of page 229, and the movement still has another 54 pages to go! Trying to work out what's what in the remainder of the movement was beyond me – I can spot fragments here and there, but the parallel material doesn't match at all. It looks like pretty much the whole of the movement on the recording has been a massive cut-and-paste job whacked together from fragments of the score somehow made to fit together. At least it all seems to get back together in time for the closing seven or eight bars, though.
Anyway, the complete movement runs to 390 bars. Up to the cut at 29m21s, we've had 143 bars of score, of which only 96 bars have been recorded. Assuming the average tempo of the missing bars to be the same as those recorded (and this is likely to be more inaccurate than the earlier estimates!), an approximate duration of the whole movement would be
22m24s.
4th movement (page 284 to 415):1: at 34m20s, at figure 9 (page 306), it jumps to eight bars after figure 9 (page 309). This, obviously, amounts to a cut of 8 bars.
2: at 35m12s, at figure 11 (page 312), it jumps to figure 13 (page 315). This amounts to a cut of 17 bars.
3: at 36m15s, at figure 15 (page 318), it jumps to figure 30 (page 369). This amounts to a cut of 312 bars.
4: at 37m25s, at figure 31 (page 373), it jumps to figure 38 (page 390). This amounts to a cut of 157 bars.
5: at 37m58s, at figure 40 (page 395), it jumps to figure 42 (page 399). This amounts to a cut of 26 bars. And that's the final cut, the remaining sixteen pages of the score play out intact!
The complete movement runs to 888 bars, of which only 368 have been recorded. The duration of those 368 bars comes to 9m26s. Assuming the average tempo of the missing bars to be the same as those recorded, an approximate duration of the whole movement would be
22m45s.
If we tot up those durations, an estimate for the duration of the uncut symphony comes out at 83 minutes, which really is quite a difference from the recording as we have it at just a few seconds shy of 40 minutes! Of course, I wouldn't necessarily take that estimate as a particularly accurate estimate, but treated as a ball-park figure it's a good guide to the extreme cuts that have been made.
Hope that information is interesting (it was a fascinating exercise to compile it all!), and of course let's hope that one day we'll get to hear the full 83 minute epic!
All the best.
