Cups Used In A Song!!

I've recently just heard of this duo called "Lulu and the Lampshades" (Supposedly, they are now called "Landshapes").  And by recently, I mean I've just watched their most popular video in the past twenty minutes.  

I have a small obsession with the upcoming movie, Pitch Perfect.  This is one of the songs that Anna Kendrick sings...I previewed it on Amazon.  I thought it had a pretty tune so I Googled it  to see who originally sang it.  The video below is one of the things that came up.

It's amazing actually how they incorporated cups into their song.  Using them as an instrument.  Enjoy!!

For those of you interested I'm also posting a cover of the song above.  I, personally, thing it's equally as good.  :)
