Ever since Tony Iommi's lymphoma diagnosis, the band was forced to pull out of many appearances, however they did promise to play one U.S. date in August. Today, a lineup for this Summer's Lollapalooza, the yearly destination festival in Chicago, IL allegedly leaked and look who is at the very top of the list? Well, two down after Red Hot Chili Peppers and The Black Keys… Black FN Sabbath! Could this be the actual lineup? It makes sense to me. The Lollapalooza officials promise to reveal the lineup on Wednesday.
