Maybe I’m just old-fashioned, but a Boston Pops concert is not the sort of event you expect fisticuffs to break out.

Something else popped at the Boston Pops opening night concert – a fight broke out in the audience at Symphony Hall.

Television video of the fight Wednesday night showed two men struggling in the balcony – one with his shirt pulled off – as several people stood around them and the orchestra and singer-songwriter Ben Folds performed a medley from the movie “Gigi”.

Conductor Keith Lockhart briefly halted the performance while the men were escorted out.

Witnesses said they heard a scream from the balcony, and the sound of chairs falling, then a second scream as the fight escalated.

“The first time there was a scream, Keith looked up that way but he kept going,” audience member June MacIndoe told Boston’s WHDH-TV. “Then about a minute and a half later … there was a big scream and you could hear chairs falling over and you could see them up there, fists going.”

Unfortunately, the story doesn’t explain why the fight started.  I can just see these guys getting into it over something like viola vs cello.

Viola rules, dude!

No, screw you, cello rocks!

Viola!

Cello!

Viola guy throws a wild haymaker at Cello dude and now it’s ON…
