I heard it for a few minutes about 12 years ago while going through
the mall to get to the carousel but it was silent when I got there
after a crew change.  The white-haired couple operating the carousel
lied and said it did not work at all and could not be played at all.

The sample I heard was tolerable by American band organ standards and
not particularly worse than a heavily played Wurlitzer band organ.  On
the same trip I rode the Lakemount Skyliner coaster, also from Roseland
Park.
