Former Beatles George Harrison and Ringo Starr used to be known for flower power and their psychedelia back in the '60s and the days of yellow submarines and "the girl with kaleidoscope eyes". These days, some 30 years on, it's still flower power, but of a more leisurely kind. George and Ringo are keen gardeners, which is why they teamed up and made a special trip to this year's Chelsea Flower Show in London. Appreciably greyer, neither of them looked like the hip kids who changed the world with their mop top haircuts and "Love Me Do" sound. With them at the show were George's wife, Olivia and Ringo's wife, Barbara Bach.
