You don't seem fully aware of history. Jon was listening to Doc McGhee in th 80's and early 90's and was the one who fired him on the night they got the Video Vanguard award and took over the reigns in full to save the band. The band never broke up in 1990, they went their separate ways to recover from the previous two tours. No one ended anything. Everyone in the band, when asked, denied a breakup and referred to it as a hiatus. Jon had enough sense to see what needed to change for them to continue and he fixed it.
