British singer Joe Cocker is dead at age 70.

His London-based agent, Barrie Marshall, said Cocker died early Monday of lung cancer in Colorado, where he has lived for the past two decades.

Cocker was known for a memorable Woodstock performance and cover of the Beatles' ``With a Little Help From My Friends.''

The ballad ``You Are So Beautiful,'' with Cocker's voice cracking on the final emotional note, was a Top Ten hit in 1975. He reached the top of the charts in the 1980s with the duet ``Up Where We Belong,'' with Jennifer Warnes, that appeared in the movie ``An Officer and a Gentlemen.''

Cocker also had hits with Randy Newman's song, ``You Can Leave Your Hat On'' and ``When the Night Comes.''
