The musician, 78, has revealed he must raise $3,000 (£1,900)-per-month to cover medical costs for himself and his wife, Lana.

Dale is coping with renal failure, diabetes and the after-effects of two bouts with rectal cancer, while his wife suffers from multiple sclerosis.

He tells the Pittsburgh City Paper, "I can't stop touring because I will die. Physically and literally, I will die.

"I have to raise $3,000 every month to pay for the medical supplies I need to stay alive, and that's on top of the insurance that I pay for. The hospital says change your patch once a week. (But) if you don't change that patch two times a day, the faecal matter eats through your flesh and causes the nerves to rot and they turn black, and the pain is so excruciating that you can't let anything touch it. That has happened to me because I was following the orders of the hospital."

Dale, whose hit Misirlou features on the Pulp Fiction soundtrack, admits he's open about his medical battles because he hopes his predicament will inspire others coping with pain and medical issues.

He adds, "I'll talk about it onstage. I'll tell them (fans), 'I don't want to see anybody complaining about anything because I'm up here jumping around like a dummy'.

"I was told 20 years ago that I wouldn't live much longer, but here I am. I believe our maker has kept Lana and I alive to give hope."
