When local singer-songwriter Colin Boyd sings Johnny Cash's "Ring of Fire" during one of his various regular engagements around town, you'd swear he'd gotten the song mixed up with James Taylor's "Fire and Rain." In fact, no matter what song Boyd happens to be singing, you'd swear he'd gotten it mixed up with a James Taylor song. The fact is, Boyd makes Jackson Browne sound like speed metal. We've seen stains that are tougher. Maybe it's not that big a deal when Boyd is running through a cover of, say, Christina Aguilera's "Genie in a Bottle," but when he's tackling The Man in Black's body of work (during a recent appearance at St. Pete's Blue Marlin, Boyd offered versions of "Ring of Fire" and "I Walk the Line," and we were only there for a half hour), we must take exception. It's like watching Hugh Grant star in a remake of The Searchers. No thanks.
