BELFAST — If you’ve been around Midcoast Maine the last decade, you’re probably familiar with Mondaynite Jazz Orchestra, better know as MoJO. For the uninitiated, MoJO is an 18-piece band reminiscent of the classic swing bands of the 1940s — think Glenn Miller and Duke Ellington, with lots of modern songs added in for fun and excitement.

On Thursday, Aug. 11, MoJO brings all those horns, drums, guitars and singers for a romp through the ages at Belfast Summer Nights. Opening for MoJO is Michael Cressey, a former Belfastian singer-songwriter who has been penning great tunes for more than 45 years. This past year he wrote a humdinger, “Tough Town,” about the Belfast of the chicken days — there is no way Belfast Summer Nights can pass that up! Cressey will be backed by two Belfast Summer Nights’ long-time favorites, Willy Kelly and David Lewis. Come hear Cressey’s songs and ponder how the community has changed over the decades.

The show starts at 5:30 p.m. at Steamboat Landing Park, 34 Commercial St. Do bring a picnic, something to sit on, friends and family, a good attitude and dancing shoes. Do not bring your dog.

No admission is charged, though a hat is passed for free-will donations. This concert is made possible with the support of First National Bank and First National Wealth Management, the City of Belfast and fiscal sponsor Waterfall Arts.
