Have you ever wondered what "Supercalifragilisticexpialidocious" might sound like as a heavy metal song?

Well… wonder no longer!

For hilarious reasons that are not clear, someone named Sera Hatchett has dubbed her voice over that of legendary actress Julie Andrews for an unexpected rendition of this Mary Poppins classic.

Check out the clip below and be warned: Dick Van Dyke does not come away unchanged, either:

Last Sunday, of course, Lady Gaga also honored Andrews by singing a medley of hits from The Sound of Music, belting out such tracks as "The Hills Are Alive," "My Favorite Things" and "Edelweiss." She ended on a very high note with "Climb Every Mountain."

That performance was widely praised by nearly everyone… except producer Shonda Rhimes.

"I had just spoken to Julie on the phone the day before and she was telling me to just relax and enjoy myself and then when she came out at the end, it was the perfect moment. I can’t even explain it," Lady Gaga said of her tribute. "It was a dream come true. It was a surprise."

We have not yet heard from Hatchett regarding this unusual take on "Supercalifragilisticexpialidocious."
