After a four year hiatus from television, Gap is making a big comeback with these new spots for their “Back to Blue” campaign. Created out of PMH and directed by Danny Clinch, the progenies of musical legends reinterpret their parents’ songs; Billy Joel’s daughter Alexa Ray sings her own rendition of his classic tune “Just the Way You Are,” and Dhani Harrison, son of George Harrison, performs his take on “For You Blue,” from The Beatles’ album “Let It Be.”
