Sparta is an American rock band from El Paso, Texas, formed in 2001. Founding members Jim Ward (vocalist/guitarist) and Tony Hajjar (drummer) are also members of post-hardcore group At the Drive-In. Keeley Davis (guitarist) is the former frontman of Engine Down. Using only the above description and what you know about the world, "Jim Ward and Tony Hajjar have never been in a band together." is definitely correct, incorrect, or inconclusive?
