LOS ANGELES — Bruce Langhorne, an influential session guitarist who often collaborated with Bob Dylan and inspired his song “Mr. Tambourine Man,” has died. He was 78. A family friend said that Langhorne died last Friday at his home in Venice, Calif., of kidney failure.

A mainstay of the Greenwich Village folk rock music scene in the 1950s and 1960s, Langhorne played with the likes of Joan Baez, Gordon Lightfoot and Buffy Sainte-Marie, among others.
