Flashback Friday has been taken to a whole new level in the Glee series finale.

The final episode of the Fox musical dramedy will feature a stroll down memory lane to when Will Schuester (Matthew Morrison) began forming the New Directions – and PEOPLE has an exclusive First Look.

In the clip, Artie (Kevin McHale) auditions with a rendition of Ginuwine’s “Pony” that Mr. Schu calls “soulful.”

The episode will also feature a large group number with a parade of returning guest stars.

“It was waterworks,” Lynch recently told PEOPLE of filming the finale. “There are some takes I’m sure they can’t use because we were all weeping. It was hard to get through.”

The final episode of Glee airs Friday at 8 p.m. ET on Fox.
