Clapton Knocking On Heaven's Door!

Rocker, 72, confined to wheelchair and fighting to breathe.

SLUMPED in a wheelchair and looking deathly ill, 72-year-old guitar hero Eric Clapton appears ready to take his final curtain call, alarmed fans fear.

“Looks like he’s not for this world much longer,” says a devotee.

“Decades of drugs, sex and rock and roll have caught up with him. He looks 90.”

Another who believes the I Shot the Sheriff rocker is near death’s door, says, “He needs our prayers.”

Eric was barely recognizable as he was wheeled through Los Angeles International Airport on March 29, heading back to England hours after canceling two concerts at the last minute.
