Rock legend Roger Daltrey has advised Prince Charles “Don’t let the b***ards grind you down”.

The musician who credits Homeopathy with saving the life of his son, gave his advice to the Prince of Wales  when he was guest speaker at an event staged by the Prince’s Foundation for Integrated Health.

He told how he and his wife were left in despair when their then eight-month-old boy Jamie developed an intestinal problem which had doctors baffled.

"I was aware of homeopaths, but I thought where do I find one and I had to look in Yellow Pages," the 65-year-old musician recalled."He prescribed some powders and within two days my son was keeping food down and within two weeks he was starting to put on weight and come back to life."

Addressing the conference about his experience with Homeopathy, Daltrey praised Prince Charles for his work campaigning on issues like integrated health and climate change.

The Who's lead singer described the heir to the throne as "his own man" when the two met at the  health conference in central London.

Asked what he thought about the 60-year-old Prince, Daltrey said: "I think the work Charles is doing is amazing, he takes it on the chin, he's his own man” before jokingly advising “Don’t let the B****rds grind you down”.
