Well, I will not deny that I observed some peculiarities. The technique of the purported guitarists looked remarkably similar and the left hand alone was enough to give me pause. Oh well, interesting in any case. Further sleuthing might be useful. Anyway, I love Manolo de Huelva's playing along with my favourite----Diego del Gastor.

Some good comes out of it - as I said, the audio is authentic, so at least you get to hear some fine singing and playing.
