It's finally here: McKinley High's prom! What can viewers expect from the 'Glee' prom episode? Lots of drama, a very popular Adele song, ABBA and, oh, did we mention drama?!

Jesse and Rachel perform a duet of Adele's 'Rolling in the Deep,' and Mercedes and Santana take the leads on ABBA's 'Dancing Queen.'

Blaine, with help from Tina and Brittany sing Black Kids' 'I'm Not Gonna Teach Your Boyfriend How to Dance With You,' Artie sings Stevie Wonder's 'Isn't She Lovely' and Rachel gets a solo on Christina Perri's 'Jar of Hearts.'

Be on the lookout for the boys to sing Rebecca Black's Internet hit 'Friday.'

Listen to the full songs after the jump.

America's terrorist watch list just hit the 1,000,000 mark. Yay! Sort of. Not really. Jon pointed out that Nelson Mandela was only recently removed from the watch list. He said it in a way like Mandela had no business being on the watch list on the first place, which I thought was a bit unfair. Sure, striking Mandela from the list was a move that probably should have happened over twenty years ago and his motivation was anti-apartheid, but once a guy has been the leader of a sabotage against his own government and military, that kind of makes the big boys of other countries nervous about having him around too. I'm just saying.

Now that we're five seasons into American Idol, NBC has realized that it's a ratings powerhouse. And it wants in on some of that action. So, NBC is bringing another European singing contest across the pond (American Idol was based on the British Pop Idol). This time, it's the Eurovision Song Contest, which launched the careers of Celine Dion and ABBA. Yeah, it's been around for a bit. 50 years, to be exact.

NBC will begin its search for talent online to find singers from each state. I'm not sure if it's the same thing as this online talent competition that NBC has planned for this summer because NBC does plan to air most of the Eurovision Song Contest on its network. Just like on Idol, voting is up to the viewers. Let's just hope they don't make Celine a host.
