Daly sings at Beatles' hangout

With four broken marriages, $US60 million lost in casinos and countless trashed hotel rooms behind him, former British Open golf champion John Daly's life story has enough material for dozens of country tunes.

Daly told part of his tale on Tuesday with a couple of songs at Liverpool's The Cavern Club, the old stamping ground of celebrated Liverpudlians The Beatles.

Daly, in town to play the British Open at the Royal Liverpool Golf Club, took the opportunity to promote his autobiography - My Life in and out of the Rough.

In a tune of his own, an autobiographical ballad called Lost Soul, Daly sang: "I lost my mom three years ago, dad pulled a gun on me."

Daly's other number was a humourous cover of Bob Dylan's Knocking on Heaven's Door with the lines "I haven't made a cut in weeks/My career has never looked so bleak" substituted for Dylan's.

He didn't trot out another self penned ditty - All my Exes wear Rolexes.

The balance of the drinking and smoking double major winner's story is told in his candid autobiography My Life in and out of the Rough.

Passages like the following detail a temptestuous life in stark contrast to the ordered lives of most professional golfers: "After a while, Dad got up and stumbled into his bedroom. We thought he was going to bed, but all of a sudden he stumbles back out of the bedroom with a big old pistol in his hand, and he points it at me, about six inches from my head. I'd had it with him. I said to him, 'Go on, just shoot me'."

The Royal Liverpool Golf Club last hosted the British Open in 1967, the year the Beatles recorded Sargent Pepper's Lonely Hearts Club Band.

Daly has never played the links course before, but despite not winning a tournament since 2004, he remains a danger to the favourites with his length off the tee and touch around the greens.
