They don’t make country singers much better than Waylon Jennings and Willie Nelson, and it’s hard to imagine a more auspicious pairing. As such, I’m particularly disappointed by WWII, which finds the duo cursed with syrupy arrangements and corny, lightweight material. There are a few exceptions, such as “(Sittin’ On) The Dock of the Bay” and Tom T. Hall’s “The Year That Clayton Delaney Died,” but most of the album is tame and tepid enough to make you forget that these guys ever ranked as Nashville’s “outlaws.”
