"There's a sign on the wall
But she wants to be sure
'Cause you know sometimes words have two meanings

In a tree by the brook
There's a songbird who sings
Sometimes all of our thoughts are misgiving

Oh ... It makes me wonder!

There's a feeling I get
When I look to the west
And my spirit is crying for leaving

In my thoughts I have seen
Rings of smoke through the trees
And the voices of those who stand are still looking

And, it makes me wonder!"

And it's whispered that soon if we all call the tune
Then the piper will lead us to reason
And a new day will dawn for those who stand long
And the forests will echo with laughter
Jimmy Page/Robert Plant - Led Zeppelin (excerpt - Stairway to Heaven)
