From the outside, it looks like Journey are among classic rock’s most indestructible battleships. Iconic howler Steve Perry hasn’t been in the band since 1998, and they haven’t hard a chart hit since two years before that. Still, “Don’t Stop Believin'” keeps going through revival after revival, and Journey can continue to headline arenas, no matter who’s in the current lineup. But Journey do have one crucial problem: The two longtime guitarists who can’t stop suing each other over access to the band’s credit card. If that happens enough times, it’ll inevitably interfere with your touring plans.
