Brad Paisley surprised his full-house audience at London's O2 Arena on Wednesday (August 17) when he brought out a special surprise guest during an encore -- Rolling Stones guitarist Ron Wood. The rock icon and the country superstar performed 'Let the Good Times Roll' and Brad's hit 'Alcohol' with a little help from Darius Rucker.

Watch the tour guitar slingers let loose in the video below.

While Ron Wood is a London legend, Brad has been enjoying a degree of anonymity in the city. Sometimes, even the security staff didn't recognize him. "I should have a laminated pass backstage over here because I'm getting asked if I belong here; 'Excuse me sir do you have a pass?'" he told the BBC. "It's humbling. It's also pleasant ... nice. I can walk around here feeling like hardly anyone is going to know me."

Brad will play Ireland, Norway, Sweden and Denmark before heading back to the States for a Tampa, Fla. show on September 9.
