Leon Russell: A half-century of musical genius that spanned from Jerry Lee Lewis to Amy Winehouse

Leon Russell called his best-known composition "A Song for You," but a better title might've been "A Song for You -- and You and You and You and You." The heartfelt ballad, instantly recognizable from its opening cascade of delicate piano notes, first appeared on Russell's self-titled debut album in 1970. That's a decade after this singer, songwriter and multi-instrumentalist -- who died Sunday at age 74 -- moved to Los Angeles from his native Oklahoma and quickly established himself as a go-to session player. Since then, though, "A Song for You" has been recorded and performed hundreds of times by artists as diverse as Donny Hathaway, the Carpenters, Willie Nelson, Amy Winehouse and the rapper Bizzy Bone. In 1994, Ray Charles won a Grammy for his moving rendition of the tune.
