El Condor Pasa (If I could) by Simon/Garfunkel, Album: Bridge Over Troubled Water (1970)

I'd rather be a sparrow than a snail
Yes i would, if i could, i surely would
I'd rather be a hammer than a nail
Yes i would, if i only could, i surely would

Away, i'd rather sail away
Like a swan that's here and gone
A man gets tied up to the ground
He gives the world its saddest sound
Its saddest sound

I'd rather be a forest than a street
Yes i would, if i could, i surely would
I'd rather feel the earth beneath my feet
Yes i would, if i only could, i surely would

A song, not directly environmental, but singer's wishes seems to be inspired by the monotonous urban environment he lives and his feelings to escape away from the everyday routine he is forced to live in. Especially the verse "I'd rather be a forest than a street" shows the huge difference of an environment full of life and variation in contrast with the monotonous paved street full of cars and pollution.

The song was an old traditional peruvian song and the artists took the music and put their completely different lyrics. They faced some foolish problems with copyright, because someone else, many decades before, has re-written the music of the song in the version Simon-Garfunkel heard it for the first time, and his descendants went them to court.
