A MUSEUM QUESTION!

[Weslicious]

LOL, I'd love to see the fans reaction if she were to neither perform 'evolution' or 'Boy's and Girls'

'OMG, How could she not perform at least one of them. I'm so dissapointed in her'

Then next year she performs both:

'Uck, she always performs them. How boring'.



If she were to perform all single tracks up to the point of A MUSEUM, there would have been 42 songs (Incl Connected, A Song Is Born). Surely you can see how such a set up wouldn't be feasible.
Only 20 of the 24 she sang were singles. It was a retrospect of her career at that point aka A museum of the songs in her career.
