This is how Jemaine plays it live. It's basically the same riff over and over with a 
finish:

G|---------|---------|---------|---------|
D|---------|---------|---------|-----2---|
A|---------|---------|---------|-3-------|
E|-5-6p5-5-|-7-8p7-0-|-1-2p1-1-|---5---4-|

G|---------|---------|---------|-------|
D|---------|---------|---------|-------|
A|---------|---------|---------|-3-----|
E|-5-6p5-5-|-7-8p7-0-|-1-2p1-1-|----4--|

G|---------|---------|---------|---------|
D|---------|---------|---------|-2---2---|
A|---------|---------|---------|---------|
E|-5-6p5-5-|-7-8p7-0-|-1-2p1-1-|---4---4-|

And repeat.

During some parts of the song like when Jemaine (the "Hiphopopotamus") is singing, the 
simplifies to this:

G|---------|---------|---------|---------|
D|---------|---------|---------|---------|
A|---------|---------|---------|---------|
E|-5-----5-|-7-----0-|-1-----1-|-0-----0-|

You pretty much just omit the pull-off thing from the main riff, and the different endings.


Sometimes this part simplifies even more so you only play the first note in each section:

G|---------|---------|---------|---------|
D|---------|---------|---------|---------|
A|---------|---------|---------|---------|
E|-5-------|-7-------|-1-------|-0-------|
