I think she probably do at least the more signature songs off each.
For OOTB: IKAG
For TD: California Gurls & Firework
Maybe some of the other singles
For OOTB: WUIV, HnC, USG
For TD: TD, ET,LFN
I doubt it will be more than 2 or 3 from each. Its obviously going to be Prism focused. so if she does mostly Prism and you would think shes going to do a cover or two. so it doesn't leave room for much more
