Rocker Neil Young insists on scheduling diary appointments according to the moon's position - despite conceding it's an annoying habit.

The HEART OF GOLD hitmaker has planned much of his creative life around the lunar calendar and irritated countless associates by refusing to leave the house when there is a full moon, no matter what his obligations may be.

He says, "If you're a writer, writing has to be Number One. That's one of the big rules.

"I never let a schedule drawn up by my manager or family members take precedence over a full moon.

"If there's a full moon I'm like, I'm not going tonight.

"It causes a few problems in the short term, but if you're so into what you do that you can't stop, then it's alright.

"You have to have understanding people around you."
