Sir Paul McCartney and Ringo Starr led the list of celebrities reacting to the passing of rock legend Joe Cocker Monday.

The singer died of lung cancer, his agent, Barrie Marshall, confirmed to FOX411.

McCartney told the Daily Mail: "It's really sad to hear about Joe's passing. He was a lovely northern lad who I loved a lot and, like many people, I loved his singing.
"I was especially pleased when he decided to cover With A Little Help From My Friends and I remember him and (producer) Denny Cordell coming round to the studio in Savile 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 for him for doing that.
"I knew him through the years as a good mate and I was so sad to hear that he had been ill and really sad to hear today that he had passed away.
"He was a great guy, a lovely guy who brought so much to the world and we'll all miss him."
