With the help of some house elves, a cup of tea (good for the throat!) was left on the bedside table of every choir member and charmed to stay the perfect temperature. Along with the tea, they would have found a handwritten note from Megan.
You're going to be brilliant!

[Delivered to all Choir Members during the concert]
Thanks again to a few house elves, when choir members returned to their rooms after the concert they would have found a chocolate rose fit for a star along with a note from Megan.
