Warm-up Faves from Choir

A student requested that I post these songs... I'm not sure if it was for the full videos or the karaoke versions. Both of these are fan favorites in choir for misc. warm-ups, especially Jar of Hearts!
I'm not exactly a fan of the Fun. video - and they are both a touch on the dark side - but I don't think they are offensive, so I will go ahead and post them...
