Scott McKenzie, who sang the 1960s hit San Francisco (Be Sure To Wear Flowers In Your Hair), has died aged 73.

The singer was a close friend of Mamas and Papas star John Phillips, who wrote and produced the San Francisco track.

Released in May 1967, it became a global hit and an anthem for the 1960s counterculture movement.

"I am amazed at how San Francisco continues even now to evoke dreams in the hearts and minds of people all over the world," McKenzie wrote in 2002.
