To use the term crossover for Listen Up is a little bland. How about we use extreme crossover? That comes closer to describing a group whose Jewish roots are found in Hebrew chant, whose rhythmic roots are Klezmer, whose environmental roots are doo-wop, and whose goofy roots are country. Thus we find a liturgical blessing mixed up with 'Under The Chopah' (if the Drifters performed at a Jewish wedding), 'Jewish Food Jive' which stereotypes most of the traditional cuisine, and back and forth among the religious and secular leavened with with a heavy dose of humor throughout.
