“Glee” begins its sixth and final season on Jan. 9, and in preparation for its farewell, the show released the first full performance featuring Darren Criss, Lea Michele and the Warblers. The group tackles Ed Sheeran’s “Sing,” the lead single from the British star’s “X,” which came out in June.

In the clip, Blane (Criss) is the Warblers’ new coach, and the group performs a pretty impressive dance routine for him and Rachel (Michele). Enjoy, Gleeks.
