Joe Cocker, whose career spanned 40 years, has died after a long battle with lung cancer.Cocker, known for his rasping voice, rose to fame with his cover of the Beatles song With a Little Help from My Friends, which went to No 1 in 1968.A longtime US resident, he lived on a ranch in Colorado with his second wife, Pam. His death, aged 70, was confirmed by his agent, Barrie Marshall, who represented the singer for more than 30 years and said Cocker was “without a doubt the greatest rock/soul voice ever to come out of Britain – and remained the same man throughout his life. Hugely talented, a true star, but a kind and humble man who loved to perform. Anyone who ever saw him live will never forget him.”
