Stuff they would probably have to do on a farewell:

Runaway
Bad Name
Prayer
Wanted
Bad Medicine
I'll Be There For You
It's My Life
Who Says

Stuff they will probably do:
Raise Your Hands
Lay Your Hands On Me
Born To Be My Baby
Blood On Blood
Bed Of Roses
Keep The Faith
I'll Sleep

Stuff Jon will want to do:
Lost Highway
We Got It Going On
Born To Follow
This House

Stuff they might do:
Always
These Days

Never Say Goodbye acoustic would be nice....

So based on that.....

I would say...

Blood On Blood
This House
Bad Name
Born To Follow
Lost Highway
It's My Life
Born To Be My Baby
Bed Of Roses
Lay Your Hands On Me (Richie Vocals)
We Got It Going On
Raise Your Hands
Runaway
Keep The Faith
I'll Be There For You
Who Says
I'll Sleep
Bad Medicine

Never Say Goodbye (Acoustic)
Always or These Days
Wanted Dead Or Alive
Prayer

Feel like I may be missing something obvious here. I know there isn't anything from 2020, and Jon might want to include something, but the album was pretty much the biggest flop of their career commercially, so I can see them ignoring it.
