Soulful rock icon Joe Cocker died yesterday, Dec. 22, at the age of 70. The singer had been battling lung cancer. Tributes began flooding in from Cocker's contemporaries: Paul McCartney, The Doobie Brothers and Ringo Starr all paid their respects on Twitter. Some of today's artists like Lupe Fiasco, Lady Antebellum and Lenny Kravitz also showed love for the legendary performer.

McCartney recalled Cocker's brilliance on The Beatles's "With a Little Help from My Friends," which the singer recorded in the late 1960s and eventually became the theme song for The Wonder Years:

I was especially pleased when he decided to cover 'With a Little Help from My Friends' and I remember him and Denny Cordell coming round to the studio in Saville Row and playing me what they'd recorded and it was just mind blowing, totally turned the song into a soul anthem and I was forever grateful to him for doing that.

Starr also chimed in on Twitter, writing "Goodbye and God bless to Joe Cocker from one of his friends peace and love."
