Update: The Thursday night lineup for the Great South Bay Festival in Patchogue was a little late in coming, but the bands are now listed at the festival’s website.

They include Kevin Devine, Minus the Bear, Manchester Orchestra and the 1990s sensation Third Eye Blind,

The acts start at 5 p.m., with Third Eye Blind taking the stage at 9 p.m.

Original story (April): Graham Nash of Crosby, Stills & Nash fame, the 1990s sensation Blues Traveler, and singer/songwriter Colin Hay — formerly the lead man for Men at Work — will all be heading to Patchogue Village in July as part of the 10th annual Great South Bay Music Festival.

Tickets are available through the Great South Bay Music Festival website and start at $32+ fees for general admission.

“Which is amazing,” said festival organizer Jim Faith. “To see Graham Nash anywhere else would be $60. We work a little harder for this festival to make it affordable for everybody.  It’s all about the music and being around next year. This is our 10th year so we must be doing something right.”

Nash will be performing Sunday, July 17, the last day of the four-day festival at Shorefront Park. He’ll be joined that night by Colin Hay, Railroad Earth and NRBQ.

Blues Traveler will take the stage on Saturday night, with the progressive rock band Umphreys McGree closing out.

Faith said last year’s festival drew about 20,000 people to Shorefront Park, up from about 14,000 the year before. Last year also saw a fourth day added to the festival. The lineup for this year’s Thursday night has yet to be determined.

“This is probably the most diverse year that we’ve ever had,” Faith said. “It will also be a more peaceful year, with families. We want everyone to smile and just have this be a great place to be on a beautiful day and night on the water.”

While last year’s headliner, 311, is a higher-energy band than you’ll find this July, Faith said the group still attracted a nice crowd with no issues.

“311 really stirred everybody up,” he said. “But when they were down everybody just walked out, tired from jumping around.

“So we’d definitely like to get them back one day.”
