Cream N. S. U. Lyrics

N. S. U. lyrics
Driving in my car, smoking my cigar
The only time I'm happy's when I play my guitar
Ahh, ahh

Singing in my yacht, what a lot I got
Happiness is something that just cannot be bought
Ahh, ahh, ahh, ahh

I've been in and out, I've been up and down
(From: http://www.elyrics.net/read/c/cream-lyrics/n.-s.-u.-lyrics.html)
I don't want to go until I've been all around
Ahh, ahh

Ahh, ahh

What's it all about? Anyone in doubt?
I don't want to go until I've found it all out
Ahh, ahh, ahh
