Earlier this week, Sweat/Pound 4 Pound Gym in St. Louis received a visit from music legend  Bob Dylan. In town for a concert, the legendary singer-songwriter and his band stopped in the gym for a boxing workout.  At age 71, Dylan is still rockin’ and rollin’ and hitting the heavy bag.  This was Dylan’s second visit to Sweat in four years, as he is known to look for local boxing gyms when on his "Never Ending" tour traveling from town to town.  Dylan knows a bit about boxing and wrote two of the best boxing songs ever: “Hurricane,” which was about the wrongful imprisonment of ex-middleweight contender Rubin “Hurricane” Carter, and “Who Killed Davey Moore?” which pinpoints everything wrong with the sport of boxing.  Dylan's song "Forever Young" was quoted by Howard Cosell in the final moments of the broadcast of Muhammad Ali's late-career victory over St. Louis' Leon Spinks.  Boxingtalk’s Doveed Linder, a trainer at Sweat, was offered tickets to Dylan's concert, but was unable to attend because he is preparing fighters for the local Golden Gloves Tournament.
