A musical threesome named the Blue Trio will provide entertainment at Sunday\u2019s Cannon Grange Agricultural Fair. The annual event will take place Aug. 24, from 10 to 4, on the grounds of the historic Cannon Grange Hall at 25 Cannon Road. Will Comer, the trio\u2019s spokesman, said they mainly focus on playing standards, varying from slow ballads to swinging be-bop. \u201cBut at the grange fair, we are trying to innovate to give the audience a special treat,\u201d he said. \u201cIn addition to playing piano, I also play accordion. So for one of our sets, we will be playing polkas and various accordion songs from different cultures. I love playing accordion and its music, and we want to bring that love that we share to the audience. But unlike typical polkas, we are also adding some jazz elements to each song. \u201cIn addition to playing the standard melody, we will be vamping off the polka while our saxophonist brings jazz improv elements to the song,\u201d he explained. \u201cIt is kind of like mixing jazz and polka practically. The music is going to be a lot of fun, and I guarantee anyone can relate to it and will enjoy it.\u201d There will also be three state baking contests and judged contests of horticulture and home arts such as sewing and needlework. There will also be contests for poultry and fowl, homemade spirits and eggs. All vegetable, fruit and flower entry items will be sold to benefit Cannon Grange. Throughout the day there will be an assortment of children\u2019s games, including relay races, a dress-up game and an egg-and-spoon race \u2014 except with Ping-Pong balls. A fair favorite is the watermelon-eating contest that begins at 3:30. Admission to the Cannon Grange Agricultural Fair is $1 per person, or a canned good that will be collected for the Wilton food pantry. There will be ample, free parking at the nearby Cannondale Station. Information: 203-762-1900 or cannongrange.org.
