User blog:KniroAndTito3915/Anyone know which version of The Little Drummer Boy this is? I need to know...

There's this version of the song "Little Drummer Boy" that doesn't have the "parumpapumpum" thing in it. It sounds like it's sung by a lady (might be two, it has some weird harmonised or multi-tone sound to it or something). It has a weird-sounding flute that plays in it. The version is slightly creepy sounding (at least to me) and kind of monotone, more than the Little Drummer Boy already is...

I want to make something funny but I need to figure out who sings this song...
