Robbie,  I failed to include one of the Standard Music Roll Co. labels
in the write-up the other day.   As an addendum, it's:

Sing-A -- red label on white paper.  All issued with words printed on
the roll, same masters as Arto and VocoWord.

Also, I didn't mention the Rhythmodik Corp. in Belleville, which of
course made the wonderful Rhythmodik (and even more wonderful Ampico)
rolls from the early 'teens onwards.
