Grateful Dead star Bob Weir thrilled fans at the Outside Lands festival in San Francisco, California on Saturday (11Aug12) when he joined Norah Jones onstage for a rendition of his classic band's hit It Must Have Been The Roses.
Weir was at the three-day event to see Jones, revealing his daughter is a huge fan of the singer/songwriter - and he was happy to team up with the star onstage.
Jones' guitarist Jason Abraham Roberts tells RollingStone.com Weir's appearance was a huge thrill for him and his bandmates.
He says, "Everybody in Norah's band are just huge Deadheads. We've actually been playing It Must Have Been the Roses almost every night, because we were like, 'We have to play a Dead song.'
"But playing a Grateful Dead song, in Golden Gate Park, with a member of the Grateful Dead? It’s pretty crazy."
Outside Lands also featured headline performances from Neil Young & Crazy Horse, Metallica and Beck.
