Reiner, apologies for not replying earlier – I completely missed any additions to this thread!    Ruth is absolutely correct about the Opera Rara recording of the 1847 version, which has the shorter ending. All the other recordings I have (Abbado, Muti, Gardelli & Sinopoli) end with the victory hymn. Abbado retains the ‘Mal per me’ (beautifully done, as you would expect, by Cappuccilli) before cutting back to the 1865 ending. When the Muti was originally released by EMI, it had ‘Mal per me’ as an appendix and, I believe, other examples from the original 1847 version, but these have not been included in the set’s most recent incarnations (presumably to fit the opera onto 2 discs). I don’t know if the original ending was one of those Muti recorded.  I didn’t know the Gardelli until I downloaded it a fortnight ago. I’d not heard tremendously good things about it, but found the performance by Elena Souliotis an exciting, if erratic, one and although, Dietrich Fischer-Dieskau is not my idea of a Verdi baritone, he does some interesting things. I very much like the Opera Rara set, expensive as it is, for the opportunity to hear that original 1847 version with many more changes than some of the other OR Verdi releases – Lady Macbeth’s ‘Trionfai!’ aria (later replaced by ‘La luce langue’ and Macbeth’s ‘Vada in fiamme’ in Act III (replacing the duet ‘Ora di morte e di vendetta’) being the most noteworthy along with the finale.

The Chelsea Opera performance could well be worth going along to. It's not listed on the RFH site as yet though.
