Intro/Verse
"When you try your best but you don't succeed..."
G|---------|----------|----------|-----------|
D|---------|8---10---8|----------|-----------|
A|-6---8-10|----------|-6----8-10|-----------|
E|---------|----------|----------|-10---8---6|

There is no bass in the chorus, which is kind of why I don't think there is a 
bass in the verse

However, the bass clearly kicks in for the beatiful, seraphim-like final 
chorus (begins 
at 3:02)

The bass mainly follows the chords but there are a couple of fills
G|------|------|------|------|------|------|------|------|
D|------|-6--6-|------|------|------|-6--6-|------|------|
A|-6--6-|------|-6--6-|------|------|------|-6--6-|------|
E|------|------|------|-6--6-|-8--8-|------|------|-6--6-|
