How are Chris Brown, Jack White, Black Sabbath, Carly Rae Jepsen and Bieber faring?
Loser: Black Sabbath
This one was doomed from the get-go. Bill Ward's contract wasn't finalized before Sabbath announced a massive worldwide comeback with the original lineup, and fighting ensued. And Tony Iommi's health continued to deteriorate, turning this so-called reunion into "Ozzy and Friends" for the majority of its confirmed dates. At least Van Halen put out another record before it canceled more than two dozen tour dates.
