On Youtube I found this : http://www.youtube.com/watch?v=KmHCW_hBPfk

but in decritption he wrote "play by ear".

Somebody have sheet music for this?

This isn't quite sheet music, but it's a tutorial for Rolling Star on piano.

It's an ok vid. But I guess it's a little better than trying to get the notes by ear.
