You know what'd be great? If they went chronologically through their discography, playing 2 or 3 songs from each album. I doubt they've had time to rehearse that many old songs though.
But imagine a playlist going something like:
1- Say Never Look Back
2 - Hexed
3 - Widdershins
4 - Suicide Bomber
5 - One Bottle And A Knee Deep
6 - All Twisted
7 - Halo Of Blood
8 - Ugly
9 - Not My Funeral
10 - Smile Pretty For The Devil
11 - LoBodomy
12 - Trashed, Lost And Strungout
13 - Are You Dead Yet?
14 - Lil' Bloodred Ridin' Hood
15 - You're Better Off Dead
16 - Triple Corpse Hammerblow
17 - Mask Of Sanity
18 - Children Of Decadence
19 - Children of Bodom
20 - Black Widow
21 - Hatebreeder
22 - Touch Like Angel Of Death
23 - The Nail
24 - Deadnight Warrior
This is like a 2h30 show, maybe even 3h. But that'd be definitely doable as a once-in-a-lifetime event, and it'd be the perfect way to "end a chapter called Bodom".
