This is Dead Dog off God Bless You Amigo by the Felice Brothers.

The hammer-on bit looks like this for G, and just do the same for C, except for like with C

e|---3-3-----3-3-|
B|---0-0-----0-0-|
G|---0-0-----0-0-|
D|---0-0-0-2-2-2-|
A|---2-0-------0-|
E|-3-3-2-------0-|

And in the outro, just add G3 to C, so it's C* = 032310 for that dissonance
