Hi Tom:
Yes, I plan to compile of those recordings. But I am not in the industry and this task takes quite a lot of time, patience and not to be discouraged. And there is no money in this kind of work.
If I am not doing it right now is because I am doing other kind of CD compilation-restorations from private collector material.
In the meantime, I can let you listen the Osvaldo Fresedo recording of "Tu disfraz" at the Grand Splendid Movie Theatre in 1928.
