The song is in the key of "E" minor. The easiest, cheapest way might be by using 3rd Position on a key of "D" diatonic. You could also use an "E" Natural Minor harmonica or 5th Position on a key of "C" or of course on a chromatic.

The notes on the intro are:

E G B A G A B
E G B (bend the "B")
A G E

On a "D" in 3rd Position:

4D 5D 6D 6B 5D 6B 6D
4D 5D 6D (bend the "B")
6B 5D 4D

That should get you started. See how you do on the rest.
