Julian Lennon is the first son of Beatle John Lennon and he was the inspiration of the song "Hey Jude." He was also the one who did a drawing of his friend Lucy with crayons, showed it to his father saying it was "Lucy in the Sky with Diamonds." He joins us to talk about a new song for his childhood friend Lucy -- who died in September at age 46. And, he performs live in our studio with collaborator James Scott Cook.
