Watch: New 'death metal' video of 'Mary Poppins' goes viral

'Mary Poppins' has gone death metal, thanks to YouTuber Andy Rehfeldt.

The new clip of the 1964 classic, starring Oscar winner Julie Andrews, called Supercalifragilisticexpialidocious, has gone viral and managed to rack up over one million views in less than two days, Stuff.co.nz reported.

Rehfeldt, who plays all the instruments, recorded the track at Endless Noise featuring vocals by Sera Hatchett and Thomas Hinds.

This isn't the first metal mash-up by Rehfeldt, as his YouTube channel also features metal versions of Kesha's 'Die Young,' Katy Perry's 'Wide Awake' and Elvis Presley's 'Blue Suede Shoes,' and "less-angry" jazz versions of 'Rage Against the Machine's 'Killing in the Name' and Eminen's 'Love the Way You Lie.'
