Well said, Kim.
And The Fifth Dimension's wonderful song is actually from the hippie-dippy '60's, the 1st rock musical by Rado & Ragni: "Hair". It was the age of the tribal love-in, be-in, tune in turn on drop out time. That was when astrology, yoga, meditation and ecology were, like, far out, you know....?
And yeah, they were ahead of their time. The 60's were - astrologically speaking - the opening guns of the Aquarian Age. The Great Stellium in Aquarius in January 1961 started it all off with a bang. (or bong?)
Cheers and best wishes,
