Hy Zaret and Lou Singer - composers of LITTLE SONGS ON BIG SUBJECTS,
ONE MEAT BALL, ATOM AND EVIL etc. are mentioned in a few Mudcat threads.
I became aware of their work in the 1940's from a 78rpm album of
Little songs, which were also sung at school.
In the 1960's a series of LPs on the MOTIVATION RECORDS label expanded
the material available, with performers including RONNIE GILBERT,
MARAIS & MIRANDA, LEON BIBB, TOM GLAZER and others.

Some of those LP's have been re-released on CD by HARBINGER records.
