Gleeks, the final season of 'Glee' is still a few weeks away, but you can pass the time by watching this new performance again and again. The new Warblers covered Ed Sheeran's 'Sing' -- and it's amazing!

We didn't think anything could top Ed's magical vocals, but as it turns out, an a cappella group performing the song (with killer dance moves, no less) is just as incredible. Their harmonized voices add a depth to the song that we love.

In the 'Glee' clip, it appears the Warblers are attempting to woo Lea Michele's Rachel Berry, but if we're being completely honest, it makes us a little weak in the knees too. We haven't been this smitten since they covered Katy Perry's 'Teenage Dream.'

Be sure to to tune into the final season of 'Glee' when it premieres on Jan. 9. Check out the Warblers' performance of Ed Sheeran's 'Sing' in the video above!
