Former Beatle Paul McCartney has revealed that he still feels in contact with the late George Harrison and regularly "talks" to the musician.

78-year old McCartney says he likes to spend time talking to an evergreen coniferous tree, which was gifted to him by Harrison prior to his death in 2001 at the age of 58, following a battle with lung cancer.

Fir no one: The late George Harrison

"George was very into horticulture, (he was) a really good gardener," the legendary Grammy winner told NPR's All Things Considered. "He gave me (the) tree as a present. It's a big fir tree and it's by my gate."

"As I was leaving my house, I got out of the car to close the gate and looked up at the tree and said, 'Hi, George,' added McCartney.

"There he is, growing strongly... That takes me back to the time when I hitchhiked with him! George and John Lennon still have an ever-present presence.

"It's lovely. He gave it to me, so I just planted it, but then, as the years go by, every time I look at it I go, 'That's the tree George gave me.' George has sort of entered that tree for me. I hope he's happy with that."

McCartney was present during Harrison's last hours in California in 2001. "Anyway, the nice thing for me when I was holding George's hands, he looked at me, and there was a smile," he recalled in a recent New York Times interview.
