(CNN) -- Joe Cocker, the British blues-rock singer whose raspy voice brought plaintive soul to such hits as "You Are So Beautiful" and the duet "Up Where We Belong," died Monday after a battle with lung cancer. He was 70. Cocker's performing career spanned some 50 years, from Woodstock, where he sang the Beatles' "With a Little Help From My Friends," to the digital-music era. He had tour dates scheduled well into 2015. "Goodbye and God bless to Joe Cocker from one of his friends peace and love," tweeted Beatles drummer Ringo Starr.
