Yup. Mac Sabbath are an LA-based band with “demonic versions of Ronald McDonald on vocals, Mayor McCheese on lead guitar, Grimace on bass, and the Hamburgler on drums,” according to the Daily Dot.

On their Facebook page, the band describe themselves as “Ronald Osbourne and the whole gang in full regalia playing all their hits like 'Sweet Beef' and 'Chicken for the Slaves' in a multi-media show with video, theatrics, audience participation and sing alongs.”
