it's just a thought - Creedence Clearwater Revival

It's just a thought
But I've noticed something strange,
Getting harder to explain;
All the years are passing bye and bye,
Still I don't know what makes it go;
Who said to wait and you'll see?
It's just a thought
But I wondered if you knew
That the song up there is you.
They can't take it from you
If you don't give it away;
Don't give it away; Ooh (It's given away.)
It's just a thought
But the word has come too late
That a bad idea will take
Just about a lifetime to explain,
And don't you see,
Good one's gonna be much longer;
Who's gonna wait, just to see?
