Johnny Cash was so determined to record a final album in the last four months of his life, he encouraged producer Rick Rubin to set up a studio in his bathroom.
Rubin went one step further, hiring a full-time engineer who would be available to the country legend whenever he felt like recording.
Def Jam Records founder Rubin reveals Cash contacted him shortly after his wife June Carter Cash died in 2003 to insist he had to work or die.
Rubin says: "Sessions were booked every day and if he woke up and felt good enough to do it, he would call up and say: 'Let's do it.’
"If he wasn't doing well enough, he'd say: 'Let's do it tomorrow.'"
The result is the upcoming American V: A Hundred Highways, which frail Cash recorded from a wheelchair while fighting the loss of his sight and diabetes.
