Song ID question

Something I've been wondering about, and maybe my google-fu is incredibly weak or everyone is just supposed to know what this song is but:
WTH was the song playing at both the start (Greece) and the end of the parade of nations at the Olympic Opening Ceremonies?  It was awesome.

ETA - This! 
Thanks, bunn, for finding the title on wikipedia. X)

This is the kind of song I need in the morning (or at least it's less creepy than listening to Rammstein's 'Mein Teil' in the morning).
