Here is the banjo part tabbed out on guitar. This is heard throughout 
the song but more importantly it makes up the main background 
noise for the verses.

e|----------------------------------------------|
B|------8---------8----------8----------8(h9p8)-|
G|----8---8-----8---8------8---8------8---------|
D|-10---------8----------6----------6-----------|
A|----------------------------------------------|
E|----------------------------------------------|

When the guitar comes in, the banjo plays the same thing, just 
playing each set (10, 8, 6) twice. Listen to song for timing.
