Led Zeppelin - Thank You
"If the sun refused to shine, I would still be loving you.
When mountains crumble to the sea, there will still be you and me."
Jimi Hendrix - If 6 was 9
"If the sun refused to shine,
I don't mind, I don't mind,
If the mountains fell in the sea,
let it be, it ain't me."
Of course If 6 was 9 came first.
