Is “Water Under the Bridge” Adele’s most cheery tune about having your heart ripped out of your chest? The “Hello” singer recorded a selection of hits, as well unreleased songs from 25, last night at Radio City Music Hall for an upcoming NBC special. From the sound of it, an older, wiser Adele knows you can celebrate the new, gaping chasm in your chest with tambourines and a smile. NBC plans to air the special on December 14, which, of course, is the anniversary of the time you and Jeremy said I love you for the first time at Storm King. Haha, it’s fine! It’s totally fine. Just smile through it. Here’s some more Adele.
