Henry McCullough Heart Attack: Wings & Joe Cocker Guitarist Critically Ill

Henry McCullough, a guitarist who spent 18 months touring with Paul McCartney's band Wings in the 1970s and performed on the hit single "My Love," is critically ill after suffering a heart attack yesterday.

Although there had been initial reports McCullough, 69, had passed away, the BBC reports the musician's sister Rae Morrison said he was still in fighting spirits.

"He's a very special person," Morrison said. "We really are very worried for him, his sister is on her way home from Florida and his brother is coming home from Glasgow."

McCullough began his career as a member of The People, a '60s psychedelic band who toured with Pink Floyd, Eric Burdon and The Animals and the Jimi Hendrix Experience.

McCullough joined McCartney's group after jamming with McCartney for some sessions. Previous to joining Wings McCullough also worked with Joe Cocker's band and has the distinction of being the lone Irishman to perform during the 1969 Woodstock Festival as a member of Cocker's group.

The guitarist was also later signed to George Harrison's Dark Horse label which released his solo album Mind Your Own Business.

McCullough has continued to work and release music in recent years. His last solo album was 2008's Poor Man's Moon.
