Wearing a thick black jumper, and a scarf wrapped around his trademark curly hair to protect him from the elements, a clearly exhausted Martin slept on the deck of the ferry between Brodick and Ardrossan.

The millionaire Coldplay star made the journey to St Molio's Church in Shiskine, Blackwaterfoot without his actress wife Gwyneth Paltrow and children, daughter Apple, 3, and 19-month-old son Moses.

He told the Sunday Mail: "I'm very upset. My uncle has just died and I've been to his funeral. It's very difficult."

He had travelled from his north London home to attend the emotional event, and the rock frontman's hit song Fix You was played during the funeral ceremony.

Martin was reported to have been close to Angus, 55, who died last Monday, months after being diagnosed with cancer.

A family friend told the Sunday Mail: "Chris had a strong bond with his uncle and he was devastated to hear of his death.

"He made a huge effort to get to Arran, taking time out from his hectic schedule, and it was well appreciated by everyone.

"He looked totally exhausted going back to the mainland on the ferry."

Chris's uncle Angus, a chartered accountant, had lived in Blackwaterfoot, on the west coast of the island, with wife Caroline.

He leaves two sons, James and George, and a daughter Lucy, who married in the same church last July.
