Happy Earth Day! Music for the day...

Speaking of Earth, tonight I watched The Planet Of The Humans on You Tube. Fact-filled fun for the whole family! ;-)

Number 9 

Big Yellow Taxi by Joni Mitchell says it all

Gotta be The Beach Boys "Surf's Up", "Don't Go Near The Water", and Sail On, Sailor".

I remember being in middle school for the original nationwide "environmental teach-in" on April 22, 1970, or the first Earth Day.  I seem to remember watching a movie on ecological threats in the gymnasium with the accompanying music being Marvin Gaye's  "Mercy Mercy Me (The Ecology)."  However, I believe that song/album came out the following year in 1971 so the assembly I am remembering must have been from the second or third Earth Day.
