Music/lyrics Joni Mitchell:

Woke up, it was a Chelsea morning, and
the first thing that I saw
Was the sun through yellow curtains,
and a rainbow on the wall
Blue, red, green and gold to welcome you,
crimson crystal beads to beckon

Oh, won't you stay
We'll put on the day
There's a sun show every second

And the streets are paved with passersby
And pigeons fly
And papers lie
Waiting to blow away
