[1] Written and sung by Grace Slick,[2] it is a tuneful rant against then-President Richard Nixon and his anti-drug initiative, Operation Intercept, that he had implemented to curtail the flow of marijuana into the United States from Mexico.

The song closes with an exhortation for the young to realize the power of their numbers, as shown by the gathering of "half a million people on the lawn" at Woodstock.

The song received little radio airplay, being banned in some states,[2] but did reach #102 on the Billboard charts.

Five months after the release of "Mexico", President Nixon requested that songs relating to drug abuse not be broadcast.

[4] Live versions of "Mexico" and its B-side, "Have You Seen the Saucers", were intended to be released on the next Airplane album;[5] however, Marty Balin left the band before production of Bark was completed, forcing a change in some of the planned material.
