Some time ago I did a "Like" on a Facebook page:

    https://www.facebook.com/MechanicalMusic 

The Facebook page doesn't come right out and say so, but I
believe that Mikey Mills is the curator of this page as it
has a prominent link to http://www.mecanicalmusic.org which
is a website Mikey announced as his own in the MMD on 120211:

At any rate, because I "Liked" the page, I get periodic announcements
when something is posted to that Facebook page.   Today's posting
is a YouTube video of an Ampico playing Johann Strauss' Tritsch-Tratsch
Polka (Chit-Chat Polka).  This is not a studio recording but the
performance is a gem and it made my day:

Can anyone tell me more about the roll or the recording session ?

Thanks,
