Chickenfoot jamming along at Rockweekend 2009 in Kilafors, Sweden. Awesome night.
They start playing "It's All Over Now" but apparently Sammy Hagar doesn't know the lyrics so instead Chad Smith starts singing on Spirits old hit "Nature's Way". I love Chads expression when he realizes that Sammy is about to end the song :-D

Looks like they had a lot of fun up on the stage that night, we sure had in the audience :-)
