Tonight at 6:30pm in Macdonald Park (Yellowstone & QB) the Aish Orchestra plays. This Yiddish-based band's website is introduced with a "Warm Up Your Simcha!" greeting.
Opening for Aish, is Yitz the Great (not kidding). A magician specializing in balloon tricks.
Not sure when Forest Hills became the Catskills circa 1974, but the band's website does have American pop music clips (In the Mood) and they do sound good.
See you there.
