Iron Maiden - Blood brothers intro bass tab

Here is the beginning riff only. I am not sure about

the other part right after this. Sorry. Also this is

my first tabs so don't be so harsh.

G:-----------------------------------------

D:-----------------5--5---7----------------

A:----2--2---5---3--3---5---5--------------

E:--0--0---3---3---------------------------

There you go. Hope it's right.
