I remember that song still got airplay in the early 1970s!
Speaking of anti-drug, Stairway to Heaven could’ve been life-altering for all of my “Stoner” classmates in high school if they only paid attention to the lyrics to which they always sang along.
That’s a real live performance and not lip-synched. I always interpreted “Kicks” to be a song about a playful cat.
