1. Look at this web page. Does this look like it?

2. If you are doing the chords, who's doing the melody? I ask because most instruments could play this, but most singers would find it too high.

3. See the third note of the song, which is on the middle line? That's a B. Wherever a measure is mostly B, play a Bm.

The second space from the bottom is an A. Wherever a measure is mostly A, play a D chord.

Those two chords will get you through almost all of the song. There's one funny bit, but before we work on it, get back to us.
