The chord progression is Ab, Db, Eb.
I usually use ska chords (muting downstrokes) when I play this song; example:

e|--x-4-x-4-x-4-x-4-x-4-x-4-x-6-x-6---
B|--x-4-x-4-x-4-x-4-x-6-x-6-x-8-x-8---
G|--x-5-x-5-x-5-x-5-x-6-x-6-x-8-x-8---
D|--x-6-x-6-x-6-x-6-x-6-x-6-x-8-x-8---
A|--x-6-x-6-x-6-x-6-x-4-x-4-x-6-x-6---
E|--x-4-x-4-x-4-x-4-x-4-x-4-x-6-x-6---

Or so on. You can find yer own rhythm. By the way, here's the lyrics:

0-0-7,
0-0-7,
At ocean eleven;
An' now rude boys 'ave a wail,
'cause them out of jail;
Rude boys cannot fail,
'cause them must get bail.

Dem a loot, dem a shoot, dem a wail (Shanty town)
Dem a loot, dem a shoot, dem a wail (Shanty town)
An' rude boy's out on probation (Shanty town)
An' rude boy bomb up de town (Shanty town)

0-0-7,
0-0-7,
At ocean eleven;
An' now rude boys 'ave a wail,
'cause them out of jail;
Rude boys cannot fail,
'cause them must get bail.

Dem a loot, dem a shoot, dem a wail (Shanty town)
Dem a loot, dem a shoot, dem a wail (Shanty town)
An' rude boy's out on probation (Shanty town)
An' rude boy bomb up de town (Shanty town)

De policeman get taller (Shanty town)
De soldier get longer (Shanty town)
De rude boys a weep an' a wail (Shanty town)
An' rude boys a weep an' a wail (Shanty town)
