“I wrote it for breakfast, recorded it for lunch and we’re putting it out for dinner.” That’s the way John Lennon told the story of “Instant Karma,” one of his most memorable songs as a solo artist and the third Lennon single to appear before the official breakup of the Beatles.

By any measure, it was one of the fastest pop songs ever to come to market.

After the departure of the 3rd Marine Division from Vietnam in late 1969, the 1st Marine Division was the only marine division left operating in South Vietnam.
