I don't know if you remember this or not, but as I kid I remember going to McDonald's and they had Ronald McDonald everything. They had books, VHS Cartoon movies, toys, the whole works. Now a days, most of the stuff has gone away but the memory remains. And for a certain group of guys, it has inspired them to create the Black Sabbath/McDonald's themed cover band, Mac Sabbath! 

Dubbed 'Drive Thru Metal', Mac Sabbath takes your favorite Sabbath song and makes it McDonald's themed with tracks like Pair-a-buns (Paranoid) and Frying Pan (Iron Man). Feast on the craziest cover band I've ever seen, Mac Sabbath!
