I see that in my posting in the October 30, 2019 MMD a very minor
change was made in the text of what I submitted that, unfortunately,
rendered it incorrect.

The word "and" following my references to the 1935 edition of Grove's
Dictionary and the 1900 edition of Baker's Biographical Dictionary
was deleted and those references were separated from the rest of the
sentence that followed them and placed at the end of the immediately
preceding paragraph right after my reference to the sheet music in the
Levy Sheet Music Collection for "Life Let Us Cherish" that attributed
that piece to Mozart.

Instead, the two references, followed by the word "and", should have
begun the sentence in the following paragraph in which I said that they
and other sources have attributed the piece to Nageli rather than
Mozart.

In other words, what I had said was that the list in the 1885 catalog
of roller organ cobs and the piece of sheet music in the Levy collection
both attributed the piece to Mozart, but the 1935 edition of Grove, the
1900 edition of Baker and other sources have instead attributed it to
Nageli.

I have listened to all of the unidentified cylinder music box tunes
that Eric Stott inquired about in the October 27, 2019 MMD and the
only one that I recognize is the eighth one. It appeared on roller
("cob") #182 for the 20-note cob roller organ under the title "Life
Let Us Cherish", and a list of cobs available in 1885 that appeared
in a catalog of that year and in many cases included composers' names
listed the composer of the tune as "W. A. Mozart" (the great classical
composer Wolfgang Amadeus Mozart, 1756-1791). Also, there is undated
sheet music in the Lester S. Levy Sheet Music Collection at Johns
Hopkins University (online at levysheetmusic.mse.jhu.edu) with a date
assigned of "1799-1803" that is headed "Life Let Us Cherish. A Favorite
Ballad Composed by Mozart. Arranged also with Variations by the same 
Author". H. C. Colles, Ed., Grove's Dictionary of Music and Musicians,
3rd Ed. (New York, MacMillan, 1935), Theodore Baker, comp., A
Biographical Dictionary of Musicians (New York, G. Schirmer, 1900) and
other sources, however, instead attribute the tune to the well-known
Swiss composer, teacher, author and music publisher Hans Nageli (1773-
1836), who wrote and published a large number of songs with piano
accompaniment. Its title in German was "Freut euch des Lebens" and it
was published in 1794.
