The bass only begins playing when he says darlin' open your eyes 
this one plays for a while then it shifts up
ADVICE SLOW DOWN THE SONG AND TRY TO PLAY THESE IN TIME

G |—————————————————|—————————————————|—————————————————|
D |—————————————————|—————————————————|—————————————————|
A |—————————————————|—————————————2———|—————5———————————|
E |—5—3—2—2/3—2—3—4—|—5———3———2———————|—2———————5———————|
    1 & 2 & 3 & 4 &   1 & 2 & 3 & 4 &   1 & 2 & 3 & 4 &   

Something like halfway it shifts up

G |—————————————————|—————————————————|—————————————————|
D |—————————————————|—————————————————|—————————————————|
A |—————————————————|———————————1—————|—4———————————————|
E |—4—2—1—1/2—1—2—3—|—4———2———1———1———|—————4———————————|
    1 & 2 & 3 & 4 &   1 & 2 & 3 & 4 &   1 & 2 & 3 & 4 &   


If this helped you your welcome the best bet is to play along to the song and time each of the notes with the songs notes its really hard to hear the bass in the track so i tried really hard to try to get the right ones
