There have been plenty of discussions regarding the setlist. I think I have posted my views on it. Simply put, there are LESS THAN 10 BJ songs that cannot be dropped (and won't be dropped forever after):

1. Bad Name
2. Prayer
3. Wanted
4. Bad Medicine
5. It's My Life.

That's it! I had put KTF in that group before, but I've seen that it can actually be dropped.

The one song that keeps re-appearing in the regular rotation is Sleep When I'm Dead and I am still sure this song can be dropped or replaced. It was not a number 1 hit (unlike Bad Name/Prayer/Bad Medicine), it was not a comeback hit (unlike IML) it wasn't even as essential as Wanted (which marked the first success of a JBJ/RS collaboration without DC).

Assuming the regular set list has 20 songs (worst case scenario here, I am aware that they play about 22 songs). Let's say they play those 5 songs mentioned above, plus 5 new songs (has to be done, promoting new album). They still have 10 slots to fool around with! And from what I know, BJ is a seasoned band, they can play more than just 10 songs (without any rehearsals) to fill in those slots!

The only logical argument against changing the setlist is the lightings, but then again Bon Jovi isn't Iron Maiden who has tons of props that have to appear at certain times of the show, so I don't think the lighting restricts them that much. It seems that it all boils down to what Jon wants to do on each night and I have no idea why he wouldn't want to take chances in varying the setlists. The band is capable, why hesitate?
