Best bet to get the authentic sound is to play this with 2 guitars.
One guitar covers the melody, the other one covers the bass notes.

Gtr. I

e|-------------14----------------------19-------------|
B|-12-15-14-15----15-14-15-12-15-14-15----15-14-15----|
G|----------------------------------------------------|
D|----------------------------------------------------|
A|----------------------------------------------------|
E|----------------------------------------------------|


Gtr. II

e|----------------------------------------------------|
B|----------------------------------------------------|
G|----------------------------------------------------|
D|----------------------------------------------------|
A|----------------------------------------------------|
E|-7---3-------------------5---7----------------------|

Tricky part is hitting the 19 and keeping in time, but with practice
you guys can handle it. Listen for the timing on the bass notes.

Enjoy it!
