La chanson est devenue l'icône du Summer of Love et du mouvement hippie, dont l'épicentre se trouvait dans le quartier de Haight-Ashbury, à San Francisco.
San Francisco (Be Sure to Wear Flowers in Your Hair) est une chanson de Scott McKenzie, écrite par John Phillips, membre de The Mamas & the Papas, pour promouvoir le Festival international de musique pop de Monterey. Sortie en single en 1967, elle connut un succès foudroyant

If you're going to San Francisco
Be sure to wear some flowers in your hair
If you're going to San Francisco
You're gonna meet some gentle people there
For those who come to San Francisco
Summertime will be a love-in there
In the streets of San Francisco
Gentle people with flowers in their hair
All across the nation
Such a strange vibration
People in motion
There's a whole generation
With a new explanation
People in motion
People in motion
For those who come to San Francisco
Be sure to wear some flowers in your hair
If you come to San Francisco
Summertime will be a love-in there
If you come to San Francisco
Summertime will be a love-in there
