Mary Poppins is one the the world's most beloved films, and Julie Andrews' beautiful performances from the soundtrack have been covered countless times.
But this latest re-jig of one of the movie's most iconic songs, Supercalifragilisticexpialidocious has taken things just a bit too far.
Musician Andy Rehfeldt reimgined the song as a death metal anthem, and although he does prove a good point about how versatile music can be, we're not sure we're too happy with him ruining our favourite film!
Have a listen… and if you're really feeling it, turn the music up and get headbanging! We won't tell Julie Andrews, promise.
