“This came in 1967. We were in this lady’s house and we had all taken peyote. We were listening to the Stones’ “Satanic Majesties” and Procul Harum. This lady started having a bad experience so I grabbed my guitar and I started playing that melody. I called it “The Mushroom Lady.” I never used it. Then in 1975 we were in Europe and I played it to the band. I took the title out and called it “Europa” because we were in Europe but it came from trying to cool a lady down from a bad trip.”Carlos Santana (73)
