Well I could be wrong but I'd guess the majority of the songs will be from the boxset. With the TLFR show they did mostly the TLFR songs, along with a few acoustic other songs too, but basically just TLFR.

There are a lot more songs on the boxset so if they want to do a good show I'd bet they play mainly those ones. I can't wait to see it, although I haven't got my boxset yet so wouldn't recognise all of the songs
