Hi Sandtreader
In the beginning I want to say, moby dick songs are spectacular, I think they get us close to origins, which doesn't necessarily are superharmonic, and echoed on microphones, they just great.
About the movie about A L Lloyd is scheduled this evening, The first couple minutes just confirms is a great source of knowledge (if you have more movies like this please share).
I didn't use falsetto till now because "not low enough voice syndrome", but if I listen, A L Lloyd, I definitely start using it.
