The Rolling Stones face a $320,000 (£200,000) fine after their historic 50th anniversary concert in London ran 35 minutes over time.
The (I Can't Get No) Satisfaction hitmakers played an electrifying gig at the O2 Arena in Greenwich for more than two hours on Sunday (25Nov12) but started half an hour later than planned.
The rockers were due to wrap up their performance at 10.30pm but defied local council regulations to play encores for the 20,000 cheering fans until 11.05pm.
The late ending broke a Sunday night curfew laid down by authorities, meaning the band now faces a hefty fine.
Rolling Stones agent Bernard Doherty tells British newspaper The Sun, "It means a big fine - but the guys just do their thing. There wasn't a janitor standing there, jangling his keys, saying, 'I want to go home'."
Fellow musicians Bruce Springsteen and Sir Paul MCCartney were penalised in July (12) when their microphones were cut off after the Hard Rock Calling concert in London's Hyde Park over-ran.
