A long and impressive list of artists — including a few unannounced special guests — sang 26 George Harrison songs for about three hours Sunday at L.A.’s Henry Fonda Theater. The George Fest fundraiser for the Sweet Relief charity, which helps professional musicians in need, is the fourth in a series of Best Fest tribute events organized by New York’s Cabin Down Below Band that also have included Dylan Fest, Petty Fest and Stones Fest.

George’s son, Dhani Harrison, was a major presence during the evening, singing “Let It Down” and “The Ballad of Sir Frankie Crisp (Let It Roll)” from George’s All Thing Must Pass album and The Beatles‘ “Savoy Truffle” before returning at the end to kick off ensemble renditions of The Traveling Wilburys‘ “Handle With Care,” followed by “All Things Must Pass.”

Norah Jones was one of two daughters of Harrison’s good friend Ravi Shankar who performed. She sang “I’d Have You Anytime” with singer-actress Karen Elson, “Behind That Locked Door” and then was joined by Elson and Jillette Johnson for “Something.” Gingger Shankar, Jones’ half-sister, played double violin behind The Flaming Lips‘ version of “It’s All Too Much.”

Norah, Danny and Elson also joined in on “Here Comes the Sun,” sung by Janes Addiction frontman Perry Farrell, one of the surprise guest singers who appeared during the show. The other was Conan O’Brien, who, joined by his guitarist and band leader Jimmy Vivino, kicked off the evening with “Old Brown Shoe.”

Four Rock and Roll Hall of Famers took part — The Beach BoysBrian Wilson and Al Jardine, the latter an unbilled guest, led an ensemble performance of “My Sweet Lord,” while Heart‘s Ann Wilson performed “Beware of Darkness,” with fellow Hall of Famer Guns n’ RosesMatt Sorum on drums. Sorum also backed Strokes‘ guitarist Nick Valensi on “Wah Wah.”
