I have just this short excerpt and i wasm't even aware that there were other parts. It would be wonderful if you could manage to "chop" up you 20 minutes film and post it. If you do so, please let me know.
No resemblance whatsoever with the characteristic voice of Galeffi. It would really have been great with a preserved live performance of that great singer. Enrico de Franceschi ought to be the correct baritone, since he sang Rigoletto in Berlin 1931 and it sounds familiar comparing to other recordings with him.
