I once bought a score of the work in Pazris but gave it to theMeyerbeer Club as I never expected to hear it.
Creators were Emma Calve, Victor Maurel, Eduard de Reszke.
I look forward to recording it.
Does the Meyerbeer Fan Club still have the score, do you know? A Dubois opera is an interesting thought. Here's (http://www.youtube.com/watch?v=Pj2gSumMuOk) an aria from Aben-Hamet. Could be from Samson et Delilah.
As to that, the vocal score of his 1895-premiered Idylle dramatique Xavière is up at Sibley Library and IMSLP.
