Singer Scott McKenzie, best known for the 1967 "Summer of Love" anthem, "San Francisco (Be Sure To Wear Flowers In Your Hair)," died in Los Angeles on Saturday (August 18th) at age 73, according to Noise 11.

Since 2010, McKenzie had suffered from the extremely rare Guillain - Barre syndrome -- a non-trauma-related paralysis.

McKenzie, whose given name was Philip Blondheim, only scored one other Top 40 hit with "Like An Old Time Movie," which topped out at Number 24, and like "San Francisco" -- which peaked at Number Four -- was written and produced by old friend John Phillips of the Mamas And The Papas. MacKenzie and Phillips were bandmates in the early-'60s groups the Abstracts -- who went on to become the Smoothies, before the pair formed the Journeymen, who recorded three albums for Capitol Records before splitting in 1964.

In 1986 McKenzie went on to join a latter-day version of the Mamas And The Papas, and co-wrote with John Phillips, Terry Melcher, and Mike Love, the Beach Boys' comeback hit, the 1988 chart-topper, "Kokomo."
