In an interview with The Mirror, the 78-year-old singer recalled the moment revealing that it was a thrilling experience to have her sister Mary on stage as he completed this leg of his tour.

He said, "At 96, she's a rock 'n' roll stage and loving it. She had and continues to teach me in life."

Rob is the youngest of five siblings. He has two living sisters, Mary and Peggy. His brothers, Bob and Don, died last year just two months apart.

In an Instagram tribute to his brothers, he wrote, "I have lost two of my best mates in the space of two months. RIP Don and Bob irreplaceable buddies."

Later he explained that statement in an interview with People magazine and via an Instagram post, that he wasn't planning to retire but was actually talking about switching genres for his next album.

The album featuring pianist Jools Holland is set to be released on Valentine's Day 2024.
