It is very interesting. I study such things as often as i can. I will watch and comment later.

I liked seeing the equipment. Does anybody know if those items could still exist today? I wondered how they make optical sound. I have technicolor optical sound films from 1974 for oldsmobiles. The sound quality is very good. I know they made such to at least 1979.
I also like al jolson but it seems a bit odd to see that black face make-up. It is amazing how different everything is just 80 short years later. Groucho was right... time fly's! Or was it... time flies like an arrow, fruit flies like a banana :banana:

I would hope they do exist....... Most of it is BETTER than the crapola out now!!
