Something else popped at the Boston Pops' opening night concert -- a brawl broke out at Symphony Hall.
Before rocker Ben Folds appeared as a special guest Wednesday night, two men did some rockin' 'n' rollin' in the balcony as the orchestra performed a medley from the movie "Gigi."
The fight started after one of the men tapped the other on the shoulder with a program to complain about noise, police said.
Conductor Keith Lockhart briefly halted the performance while the men were escorted out. No charges were filed, police said.
The concert resumed, and Folds performed later.
