Capo on the Third fret.

The picking Pattern I thought worked well would be this relative to the capo:
e|-------------0-------0---------0-------0--------0---------0-------0--------0-------|
B|-------------------------------------------1--------1------------------------------|
G|-----0----------0---------2-------2----------2--------2------0-------0-------------|
D|--------2----------2--------2-------2----3--------3------------0--------0----------|
A|---3----------3---------0-------0--------------------------2--------2--------------|
E|-----------------------------------------------------------------------------------|
Repeat until the end.

The chord shapes are C, Am, F, and G

Enjoy.
