Throughout the past few decades, Bob Dylan has kept his fans guessing what songs he's likely to pull out in concert. On Thursday (June 9) at the the Greek Theatre in Berkeley, Calif., he and his band launched into a bit of Lynyrd Skynyrd's Southern rock classic, "Free Bird."

In the video above, you can see them jamming over the distinctive chords that make up the closing guitar blowout. According to setlist.fm, it took place during "Love Sick," which was the final song of the evening. Of the 20 songs Dylan played, seven of them came from his two collections from the Great American Songbook -- Shadows in the Night and Fallen Angels -- 10 were from his post-1996 output of original material and only three -- "She Belongs to Me," "Tangled Up in Blue" and "Blowin' in the Wind" -- stemmed from the '60s or '70s.

Dylan will remain on the road through July 17, when the latest installment of his Never Ending tour winds up in Gilford, N.H. In October, he will participate in Desert Trip, a three-day festival that brings together Dylan and five other rock legends -- the Rolling Stones, Paul McCartney, the Who, Neil Young and Roger Waters -- to the Empire Polo Club in Indio, Calif. Dylan and the Stones are slated to perform on the first night, Oct. 7.

Released on Lynyrd Skynyrd's 1973 debut, "Free Bird" has become one of the most requested songs at all rock concerts. Skynyrd guitarist Gary Rossington admitted that it fills him with pride that people shout out the song. “It’s kind of embarrassing if you’re with the band that’s playing,” he said. “But it’s a great honor and it’s great that people do that. It’s funny, I hear it not just at concerts, but at movies or anywhere there’s a crowd.”
