This is an easy song to play.
Standard tuning (EAGDBe)
Intro : B - Fm - Fm - E (it's like this almost the whole song)
B Fm Fm E
Come on now, don't you want to see,
B Fm Fm E
This thing that's happening to me,
B Fm Fm E
Like Moses has power over sea,
B Fm Fm E
So you've got power over me,

Then, repeat the intro (if you want the solo, you can check it on the tabs here on ultimate-guitar)
And repat the same as above
B Fm Fm E
In the CHORUS it's like:
D E
And oh, oh yes I would,
E D
If I only could,
D E
And you know I would,
E D E
And baby I,
E D E
Oh baby I,
And then the intro/solo. And the lyrics again. It's quite simple
The notes on the chorus you can do it like this:
D - 557775
E - 779997
It looks closer to the sound in the music, but if you have difficulty, just do the
the way you prefer.
