Admit it, if "Encore" or "The Band" had a t-shirt, you would buy it and wear it in public. I know I would.
I'm sure I would buy one. As this group is getting over with the fans and is a huge success already, I think the t-shirts are gonna come out real soon.
And btw, to make things clear, the name of their group is The Band and their catchphrase is "Who wants an encore?" Maybe they ditched the idea of calling them as The Encore because it is too similar to The Corre.
