You heard what Metallica sounds like with Lou Reed, and even with Grandpa Abe Simpson thanks to YouTube user GrampTallica. Now take a listen to what Metallica’s “Senior Dad” would sound like with the insightfulness of Statler and Waldorf, the critical old guys in the balcony from The Muppets. Take a listen as Statler and Waldorf reflect on the recording of Lulu in the video above. In case you want more of Metallica’s collaboration with the lovable grandpa from The Simpsons, you can hear Abe’s ramblings on “Pumping Blood” after the jump.
