Pete Seeger Surprises Farm Aid Crowd at SPAC [VIDEOS]

Farm Aid continues to support family farming. This year's festival came to Saratoga Springs with a surprised performance from folk legend Pete Seeger. The 94-year-old joined Farm Aid headliners Willie Nelson, Neil Young, John Mellencamp, Dave Mathews and Jack Johnson for 'This Land is Your Land.'  Seeger even added a new verse at the end of the song, 'New York was made to be frack-free.'

A crowd of more than 25,000 turned out for the annual event that began in 1985.  Watch Willie Nelson sing 'Roll Me Up & Smoke Me When I Die' along with his final song with everyone on stage.

Jack Johnson put on a cow suit and toured the SPAC grounds. Concertgoers had no idea who they were high-fiving, but it was a great way for a star to go unnoticed, into the crowd without being mobbed.  So if you had your picture taken with the cow, you can tell your friends you met Jack Johnson.
