Watch the Warblers Cover The Wanted’s “Glad You Came” (Video)

UK band The Wanted is coming to “Glee” via the Warblers.

The band’s hit single, “Glad You Came,” will be sung by the Warblers on Tuesday’s winter finale of “Glee.” We may not like Sebastian, but we love Grant Gustin and his voice!

Next week’s episode, which shows the choirs facing off at regionals, will definitely be a big one. Click inside for more previews and clips from the episode.

Who do you think will win regionals?
