The Main Pattern (the bass's answer to the guitar part):
G—|——————————————————
D—|—5h7—5—4——————————
A—|—————————5————————
E—|———————————5—5—3——

One of the Many Fun Fills!:
G—|—————7—7—————————
D—|—5h7—————————————
A—|—————————————5—5—
E—|—————————3h5—————

And another...
G—|—11——12—12——11/14—
D—|—12——12—12——12/15—
A—|——————————————————
E—|——————————————————

And if you want to mess around with that ever so catchy violin/sax thing they used to do...
G—|—11h12h14—11—12————11———————
D—|————————————————14————12—14—
A—|————————————————————————————
E—|————————————————————————————
(sounds really nice if you funk up the end of the riff)

And of course there's this thing...
E—|—8h10—/———(slow slide down)



OKAY!!!  How about the actual song?

Verse (main figure): (very clean and bouncy)
G—|—————————————————————————————
D—|——————4———4—————————5—5—55—7—
A—|—5—/5———5———/5———/5——————————
E—|———————————————3—————————————
lather, rinse, repeat ad lib

Okay, at the end of when Dave sings the chorus "Take these chances..." over the VERSE 
figure, this is what you do... (SEE FOOTNOTE 1)
("Quieter time...)
G—|——————————————————————————————————————
D—|————————4h5—4h5h7—5h7h9—7h9h11—9h11———
A—|—2—5——5—————————————————————————————(5...back to verse)
E—|——————————————————————————————————————

Then we go back to the verse... and finally come to a full chorus: (take these chances...) 
(hold most of these notes, let them sing) (SEE FOOTNOTE 2)
G—|————————————————————————————————————————————————————————————————
D—|————————————————————————————————————————————————————————————————
A—|—2—5————2———16p14—14p11—11p9—9p7—9p7—7p4—4/2—2———2—5————————2———(verse)
E—|——————3———5————————————————————————————————————5—————3—(55)———5—

Then we have more of the Verse pattern, then the run—up:
G—|—————————————————————————————————
D—|—0h4h5—4h5h7—5h7h9—7h9h11—9h11———
A—|——————————————————————————————(5...back to verse)
E—|—————————————————————————————————

More verse stuff... then:
G—|———  People  ——————————————— No words———————
D—|——— in every ————5—5—55—7——— exchanged——————
A—|—5— direction—/5——————————5— no time...—————
E—|————————3————————————————————————3——————3—5—    

Then: "When all the little ants are marching..."
G—|———————————————————————————————————————————————————————————4———4—7—
D—|———————————4h5—4———————————4————————————5—7—5—7—5————————7———7—————
A—|———————5h7———————7———————————7—5———————————————————————————————————
E—|—3—2—0——————————————3—2—0—————————3—2—0————————————3—2—0———————————

Then more verse stuff, until...
G—|————————————————loose end loose end, cut cut!—
D—|——————4———4——————————————————————————7—(7)—7———
A—|—5—/5———5———/5—————————————————————————————————
E—|——————————————————5————3—————5————3————————————
   
  On the fence but 
  not to offend...
G—|—————————————————cut cut, cut cut——
D—|——————4———4————————————————7———————
A—|—5—/5———5———/5—————————————————5———
E—|—————————————————3————3————————————

then, the chorus, back to the verse figure for the sax solo, then the run—up to the violin 
solo: (SEE FOOTNOTE 3)
G—|——————————————————————————————————————————————————
D—|——————————————————————————————5———————————————————
A—|—5——————————5———————————5———————————5—————————————
E—|——————3———————————3———————————————————————3(hold)—

Okay, then you play the part that went under "When all the little ants are marching," 
(there are some small differences) until you get to the Am part...
   Am  G  D  Bm D  G     Bm A   D        G
G—|—————————————————————————————(roll)——————————————————
D—|——————————————————————————————————4—4—5—————5—5—55—7—
A—|—0—————5——2——5—————————2—————5————5—5—5——/5——————————
E—|————3———————————3—(55)———5———————————————————————————

and the very end...
G—|——————————
D—|—5—5——7———
A—|————————5—
E—|——————————
