Minutemen - Shit From An Old Notebook Bass

Intro/Verse
Something like this, I can't tell if its hammer-ons on the 5h7777 or not
G|--------------------7h9------|
D|----------5h7--7h9-----------| 
A|-5h7777----------------------|
E|-----------------------------|

Or 

G|---------------7h9-----------|
D|--------5h7--9---------------|
A|-57777-----------------------|
E|-----------------------------|

That part at the end, the 9 on the D then the 7h9 on the G, 
it might just be him hitting the 9 on the G twice

So maybe this
G|-------------9-9-------------|
D|--------5h7------------------|
A|-57777-----------------------|
E|-----------------------------|

or

G|-------------9-7h9-----------|
D|--------5h7------------------|
A|-57777-----------------------|
E|-----------------------------|

Next part
G|---------------------------|
D|-5-5---5-5-----------------|
A|-----7-----7--5-5-7--5-5-7-|
E|---------------------------|

Then the same thing but the last note is a 7 on the D before he switches up
G|---------------------------|
D|-5-5---5-5---------------7-|
A|-----7-----7--5-5-7--5-5---|
E|---------------------------|


Then
G|-----------------------------|
D|--5-5-7--5-5-7------7------7-|
A|----------------5-5----5-5---|
E|-----------------------------|

Last part
Hold the last note, the 3 on the A

G|-------------------------------|
D|--5-5-7--5-5-7------7----------|
A|----------------5-5----5-5-7-3-|
E|-------------------------------|
