Izebize, thank you SO much for posting a link to merchandise!

I'm going to order as much of it as I can online now so that it's less I have to worry about when I go to the concert. (There is no way in hell I could make it through the night without breaking my Adele mugs.

) This is super helpful! I hope they add the rest of the merchandise soon.
Anyways... I think we need to relax about Glastonbury. She's going to do fine, and even if the crowd isn't thrilled about her performing by the beginning, by the end, they'll be in love with her. As someone else stated, between her banter and her amazing vocals, they'll love it. Besides, there's no way that all of the concertgoers are thrilled about Coldplay being one of the other headliners. I wouldn't exactly classify them as rock.
If she did the Super Bowl, "Rolling in the Deep," "Someone Like You," and "Hello" are givens. I'm pretty sure she would do "Set Fire to the Rain" as well because she could do something visually appealing with the whole concept of fire and rain. (Although I wouldn't be surprised if she did "When We Were Young" either just because it's her favorite.) And at some point, she would bring someone out on stage. I could totally see her bringing the Spice Girls out (Bey or Bruno would be too predictable because they've both already done it twice). It would be awesome.

I really hope she gets asked to do it!
EDIT: Actually, Mike's theory about her doing "Rumour Has It"/"Someone Like You" at the Super Bowl is a good possibility too, being that people want a lot of upbeat songs. And obviously if "Send My Love" is a huge hit, she can do that, too.
