Former Beatle Sir Paul McCartney has compared his divorce from former model Heather Mills to "going through hell".
Sir Paul said he found music therapeutic
The 65-year-old told the Radio Times the experience was "a very painful thing", adding he had vowed not to talk about the split with his second wife.
"As Winston Churchill once said, 'If you're going through hell, keep going!'" he told the magazine.
The couple, who married in 2002, are trying to thrash out a settlement, rumoured to be in the region of £60m.
Sir Paul added: "The only solution is to remain dignified. If I don't keep a silence about it, I lose this idea of being dignified."
Sir Paul and Lady McCartney announced in May of last year that they were splitting after four years of marriage.
They appeared before a judge at the Royal Courts of Justice last week, amid reports that they were close to a multi-million pound settlement.
But the couple, who have a three-year-old daughter, left separately without making any comment to waiting journalists.
"It's been a difficult time," Sir Paul told the Radio Times, "but music is a great healer.
"Music is the therapy for me. In fact, going through difficulties has only concentrated my desire to make good music."
