ok. erm. there's a acoustic version of it...when she was turnig 20 that time...she played ow crazy using her a.guitar...anyone got the chords or tab for it? and it will be better if someone could upload a video..teaching how to play...

You mean the one from her Thank you My teens TV Documentary? She only played a short bit of the song. The chords would be the same that you find in the Guitar Score or the Band Score.

If I remember correctly, you already have a thread that you've started that asked about how to play How crazy. I'm thinking that I should merge it back with that thread to avoid duplication of asking the same thing.
