If I am correct (I think) Thorn has been played 16 times and Happy now 17 times.
How many shows are we in yet? It would be nice if Europe saw that number rise siginficantly, but a song that is only performed at about 20% of the shows or even less is a rarity, ok: semi-rarity, in my book. Not as rare as others, but you cannot count on getting it at your 1-5 shows you see at the tour.
