Thanks!Jose left because his father was very ill and not expected to get better. He passed away shortly thereafter (not sure on the exact timing).
They didn't show whether JR was responsible for the Def Leppard timing snafu or not, but for a guy that earns his living doing stage shows, I found it really hard to believe he could screw that one up. I think he was accepting the blame because it was his task. I have no idea who was at fault.
