Here's a truly depressing video for organ lovers. This Cavaillé Coll is in the Buenos Aires area of Argentina. (Haven't I heard about someone from there lately?) I did some searching - This unaltered CC organ has been allowed to fall into total dis-use and dis-repair. An offer of a wealthy woman to finance it's restoration was rejected by the RC Church. Extensive restoration of the basilica was carried out with no effort to rescue or even protect the organ. Latest word I found is that it still could be restored, but likely will not be.
