Some kids know how to have a good time, and they appeared to be enjoying themselves when Jewish musician Eytan Katz came to Seattle Hebrew Academy on Fri., Feb. 19. What made the concert unique, however, was that it wasn’t just kids from SHA in the audience — students from all of the area’s Jewish elementary day schools filled the gym for the morning concert that had kids dancing in the bleachers. This concert was underwritten by local developer Martin Selig and his wife, Catherine Mayer, while a fundraiser the following evening that featured Katz benefited all of the Seattle area’s Jewish day schools.
