Johnny Cash’s daughter Rosanne has unearthed – and released – a photograph of her late father with England’s King Charles III.

The singer shared the apparently candid photograph on social media – an image which captured the pair in conversation several decades ago when the royal was, of course at the time, Prince Charles.

“I’ve been debating all day whether or not to post this photo, but it’s just too good to keep under wraps”, said Rosanne Cash.

The photograph is not the singer’s only connection to the royal family.  In 2002, he released his album “American IV: The Man Comes Round”.  The title track was inspired by a dream Cash had, in which he found himself in Buckingham Palace, face to face with the Queen, who told him: “Johnny Cash, you’re like a thorn tree in a whirlwind”.
