Singer Keith Urban surprised fans during performances in Nashville, Tennessee on Friday (06Sep13) when he brought Steven Tyler and Eric Church on stage.
The You'll Think of Me hitmaker was promoting his new album Fuse a day after he kicked off the new American football season with a pre-game gig in Baltimore, Maryland by playing three sets at a trio of Honky Tonks in less than an hour.
Several hundred fans crowded around each club trying to see Urban perform, and those who got in were treated to a few surprises - during his show at Tootsie's Orchid Lounge and the Stage, the country swooner brought out Aerosmith's Steven Tyler to perform Walk This Way.
Urban told the crowd, "If we play this (Walk This Way) long enough, I'm certain a certain blues singer will come up here."
Earlier in the evening, the American Idol judge played Cumberland Park and was joined onstage by Church to perform Raise 'Em Up. The show was taped for a webcast as part of Yahoo! Music's Ram Country Live! series, and will air later this month (Sep13).
