Eddie Vedder, strumming a mandolin, started with a Pearl Jam hit [sic], "Rise." Next he traded the mandolin for ukelele from Hawaii ("It has a little birth certificate in there," he joked). Vedder then covered a James Taylor song (couldn't immediately name that tune) and Neil Young ("Rockin' in the Free World").... and a story about Ed's past when he probably wasn't paying income tax, but he wanted to become a more productive member of society. Here is his story of getting training to become a security guard in San Diego.
EDIT: Unfortunately, the video was made private. We'll leave it here in case that changes again in the future. Until such a time, please see the Tampa Bay Times article for a summary of Ed's comments.
