Andy Rehfeldt has done some pretty interesting covers in the past, namely his death metal version of "Rudolph The Red-Nosed Reindeer." Unfortunately the holiday season is not upon us, but Rehfeldt has found a simple fix to that in terms of what he covered next- Mary Poppins! Observe the death metal version of "Dupercalifragilisticexpialidocious," which sounds like a goofy Arch Enemy outtake.
