Whoa! That's a lot of information to take in, Jack Campin! Thank you.

I'm going to take some time to read through it and try to make sense of it, and also listen to some of the tunes mentioned in the article.

This one is the first one I listened to and it is similar:

I Had a Little Nut Tree

And the one Jack mentioned previously:

La Mantovana

(Note: I searched for these songs on Google and found these versions. They are probably not exactly the same as the versions shown in the article.)
