'Glee' Sneak Peek Clip: Watch a Mash-Up of 'Moves Like Jagger' and 'Jumpin Jack Flash'

Since the early days, a staple of the "Glee" repertoire has been the mash-up. Some have been great (the recent Adele "Rumour Has It/Somebody Like You" one, for example), while others have been less of a mash-up and more of one song with a single line from another song in it.

A preview clip from the upcoming episode of "Glee," titled "Yes/No," features a mash-up that falls somewhere in the middle. It's supposed to be "Moves Like Jagger" by Maroon 5 mixed with "Jumpin' Jack Flash" from that one band that actually had Mick Jagger in it. But really it ends up being mostly Maroon 5.

The number is performed by Artie (Kevin McHale), who is joined by Mike Chang (Harry Shum Jr.) and Mr. Schuester (Matthew Morrison) for some flashy dance stuff.

The clip also hints at one of the storylines for the episode, as Becky watches Artie's performance and moons over him. And why not? At this point the show is running out of people to pair up as couples.
