Oh, say can you see ... Sunchunck? Singing, well, not the "Star Spangled Banner," as this piece seems to indicate, but "God Bless America," the tune that should be the National Anthem. At Fenway Park? Yeah, you can. On July 10. When the hometown team dispenses with the bottom-dwelling Baltimore Orioles. It's a thrill, of course, playing at Fenway, something Sunchunck bassist Mike Bertolami dreamed about when he was a kid, although the Plum Island resident "never thought it would be as a musician." Of course, at this point, the Port-based power pop band is so at home with the tune that they call it "GBA." The revved-up rock version of the patriotic classic has been the emotional core of the band's performances since they came together nearly a decade ago. "GBA" was on their debut album, "On the Map," back in 2005. They've played it at every single live show since coming together in 2002. And they've performed it live at the Patriots-Dolphins game at Gillette Stadium in 2009, and during the seventh inning stretch at LaLacheur Park, home of the Lowell Spinners, during the Spinners' celebration of America's troops at their home-grown Americana Festival in 2010. This time, however, they won't be able to hide behind their instruments: They'll be doing it a cappella. Who knows? Maybe they'll give you a taste of the a capella version when they play the Grog on July 1. C'mon, dare 'em. The show runs from 9:30 p.m. until close. There's a $5 cover. Check out the Middle Street venue for more info in the show. Check out the Sunchunck web for more about the band. You heard they have a new album, right? And the game? Nah, you'll have no trouble finding that.
