In the process of scanning someone else's large and miscellaneous
collection, I ran across a rare Musicnote roll, shown here.  I see
that Musicnote had both the Musicnote and Keynote label, but I know
little else about them.

The actual musical content of this roll is an unremarkable, cloying
show tune, but the printed lyrics are intriguing for their inclusion
of musical notes on staves.
