Kinda a chord/tab mix here for just one guitar, but I think it sounds quite close.
I based this off of the "IS Acoustic Sessions" recordings.
There are only two riffs, and otherwise it's all chords.
Riff 1
e|---------|
B|---------|
G|---------|
D|-0h2-0---|
A|-------3-|
E|---------|
Riff 2
e|--------------------|
B|--------------------|
G|----------0---------|
D|------0h2---2p------|
A|---0h3---------3----|
E|-1---------------3--|
Also, for all Fmaj7s, the G string is usually hammered on.
