And All That Jazz! Jazz is America's music and the U.S. Navy Band Commodores, the Navy's premier jazz ensemble, have been performing the very best of big band jazz for the Navy and the nation for fifty years. The band is performing at Springettsbury Park's 2023 Summer Concert Series. Come join other OLLI members on Sunday, June 18th to hear this acclaimed group. Bring your own chairs to the park's amphitheater at 1501 Mt. Zion Road in York. The music begins at 7:00 but come early to get a good seat. Look for OLLI signage to sit with your OLLI friends. The concerts are free but please register on the OLLI site. Food vendors are available and the park concession stand will be open during the concert.
