Brad Paisley has joined the club. Tuesday (6/18) saw Paisley become the latest country music superstar to join the Rolling Stones on stage during the legendary rock band's '50 and Counting' Tour. He had the honor of jamming with guitarist Keith Richards and swapped lead vocals with Mick Jagger for a performance of the Stones' hit 'Dead Flowers'.

It was no surprise, as his appearance on the Philadelphia was announced last week. The mystery was which song Paisley would be performing. Fans found out just six songs into the show, as Jagger introduced Brad, and he strolled out with his guitar and a Rolling Stones t-shirt. Check it out:

Taylor Swift met up with Mick and the boys in Chicago to sing 'As Tears Go By',
Carrie Underwood joined them in Toronto for 'It's Only Rock & Roll' and
Keith Urban did 'Respectable' in Los Angeles.
