The 2017 Union Fair & Maine Wild Blueberry Festival is in its final days, running through Saturday, Aug. 26, on the grounds just off Route 17. Friday is the day blueberries reign — with a new queen in charge — and Friday night, Aug. 25, marks the annual Premier Country Show.

Sponsored by Maine’s New Country Bear radio stations, the show takes place at the track-side grandstand and begins at 6 p.m. with a trio of Maine country treasures — Chris Fyfe, Fred "Tommy" Thompson and Denny Breau.

Maine masters

Fyfe is a multi-award-winning instrumentalist, singer and songwriter, inducted into the Maine Country Music Hall of Fame and recipient of the Maine Country Music Living Legend Award. Often hired as a studio keyboardist, he also has played on stage for Johnny Tillotson, Tony Booth and Michael Twitty, among others. And he has an enthusiastic following both as a soloist and fronting his popular band.

Thompson, who grew up on the Midcoast, is Maine’s king of the steel guitar and has been performing traditional country music for more than half a century. After many years with his own dance band, the Maine Academy of Country Music Hall of Famer performs these days with Maine greats including Fyfe, Ken Brooks and Debbie Myers.

Breau, son of Hal Lone Pine and Betty Cody; and brother of late jazz great Lenny Breau, does amazing things with a six-string guitar, churning out both lighting fast guitar lines and those of tender intimacy in his carefully crafted songs. He mixes genres with ease, drawing on folk, Delta blues, country and jazz; and demonstrating a variety of distinct styles, including that of family friend Chet Atkins.

Texas traditionalist

At 7 p.m., the grandstand stage will welcome headliner Jake Worthington, the barely 20-something traditional country singer/songwriter that, on his second try, was named runner-up of Season 6 (2014) of the hit NBC-TV show "The Voice." While on the show, Worthington released three songs that reached the No. 20 spot on the Billboard charts.

Now a fully launched country music performer, Worthington has released popular singles and videos and, this year, his second EP, which debuted Top 10 on iTunes Country Albums Charts; and featured a No. 1 single, “A Lot of Room to Talk.” This year, Worthington has brought his Hell of a Highway Summer Tour to more than 25 states — and played dozens of county and state fairs, so his Union show promises to be a well-oiled machine.

The day after the Maine Premier Country Show, Worthington plays Nashville North in Niagara Falls. Then it’s back home to Texas to a full schedule that will take him from the Texas Country Cruise to Fort Worth’s Whiskey Girl Saloon. When he can, he returns to hometown La Porte, on Galveston Bay. The 2017 CMA of Texas Male Artist of the Year, who discovered his passion for traditional country while recouping from a high school football injury, still loves fishing, mudding and four-wheeling in his diminishing free time.
