I'll admit, I'm late to jump on the Glee bandwagon.  In fact, I didn't even watch any episodes of the show until a week ago.  And then I loved it so much that I watched them all back to back.  This was completely surprising to me because I generally loathe musicals.  But watching those feisty high schoolers sing and dance has inspired me....and left me slightly obsessed with the idea of a first dance mash up of a song or two.  It would be perfect if the cast could come and sing, but that is definitely not happening.  If you watch the show (or perhaps have done some sort of choir/show choir work in your past) you know what I am talking about.  I think they did a combo of Halo/Walking on Sunshine (link here http://www.youtube.com/watch?v=vRO3ueEtzu4) and also a mash up of It's My Life/Confessions (the link is here http://www.youtube.com/watch?v=o5Tqdi5NZ3Y&feature=related).  I don't know exactly what songs I would choose, but I think it would be a FABULOUS first dance.  

What songs would you choose for your fantasy first dance glee mash-up?

 The Confessions/It's My Life mash-up would be a super awkward first dance.  Isn't confessions about a guy getting his other woman pregnant?  So not the sentiment I am going for.  

Some of my favorite love songs are Just Like Heaven by the Cure and I Believe in a Thing Called Love by the Darkness and Sweet Thing by Van Morrison.  I wonder what that would sound like.  Glee kids...help me out here!
