Sag Harbor's HarborFest presents FREE live music throughout the weekend but the highlight of HarborFest live music is always Saturday night with the Lone Sharks and HooDoo Loungers. Gene Casey takes to the Southampton Town mobile stage in Steinbeck Park at 5pm and the Lone Sharks are followed up by Joe Lauro and the HooDoo Loungers - bring a chair or a blanket and find a spot in Steinbeck Park.
