Glee will return on January 17 with - SPOILER ALERT! - a proposal, as Will pops the most romantic question of them all to Emma.
But these two won't be the sole focus of "Yes/No." Look for Sam to try and woo Mercedes by joining the synchronized swim team and also by re-enacting a classic duet from the musical Grease. Listen to the show's take on "Summer Nights" below:
Among other singles that will be covered on the episode:
- "Moves Like Jagger" (by Artie)
- "We Found Love" (by Santana and Rachel)
