McKenzie was appropriately described as a one-hit wonder, although he had a long musical association with John Phillips of the Mamas and Papas.
Phillips, who wrote and produced “San Francisco,” reportedly asked McKenzie to join the original Mamas and Papas, but the singer declined.
In the 1980s and ’90s, McKenzie sang with a touring version of the Mamas and Papas fronted by Phillips.
McKenzie co-wrote “Kokomo,” a sand-and-surf celebration that brought the Beach Boys a their last major hit, in 1988.
McKenzie and Phillips broke into the business as a high school doo-wop act that later recorded several singles for Decca Records. The band then became the Journeymen, signed to Capitol Records. It was a regular act at the hungry i in San Francisco.
McKenzie’s “San Francisco (Be Sure to Wear Flowers in Your Hair)” was an omnipresent single during the summer of love. It reached No. 4 on the singles charts.
The follow-up, “Like An Old Time Movie,” also written and produced by Phillips, found airplay and some chart success, but McKenzie’s recording career didn’t outlast the era. (Phillips died in 2001.)
McKenzie’s albums were “The Voice of Scott McKenzie” (1967) and “Stained Glass Morning” (1970).
McKenzie suffered from the nervous system syndrome Guillain–Barré. He died Aug. 18, 2012, in Los Angeles.
