Guns N’ Roses goes the distance

For a band known for concerts that might start only after unconscionable waits and run until 2:00 a.m. when they’re not canceled outright, Guns N’ Roses did perhaps the most shocking and unpredictable thing of all Friday night in Worcester: They took the DCU Center stage at a somewhat reasonable hour. 10:20, to be exact. By Gn’R standards, that’s practically a matinee.
