Singer Joe Cocker, perhaps best known for recording a famous cover of The Beatles’s “With a Little Help from My Friends,” has died at the age of 70, his agent confirmed to BBC News.

Cocker’s “With a Little Help from My Friends” was the title track off of his debut 1969 album, and became the theme song for The Wonder Years. Cocker also dueted on the Grammy-winning “Up Where We Belong” from the 1982 film An Officer and a Gentleman and was known for a series of other hit songs, including a 1974 cover of Dennis Wilson and Billy Preston’s “You Are So Beautiful” and a 1969 cover of Traffic’s “Feelin’ Alright.”

Agent Barrie Marshall told the BBC that Cocker died of an undisclosed illness. Marshall said that the singer was “simply unique.” Per ITV Sony Music also confirmed Cocker’s death in a statement.

A full obituary is forthcoming. In the meantime, remember Cocker by rewatching his roof-shaking Woodstock performance of “With a Little Help from My Friends”:
