Cover art for Love lyrics by John Lennon

"Love is free, free is love"

John is obviously referring to free love, a common hippie/communist philosophy at the time.

Or it's simply a beautiful and simplistic song about love.

I think sometimes songs don't necessarily have a hidden political or otherwise meaning.

Sometimes they just are what they are.

But then again, maybe you're right. Iuno.
