Actually it is confirmed, Bobby and Jeff will be on tour with the band this time. But don't worry they were very much in the background last weekend. Bobby is situated at an angle behind Hugh and next to David, you really don't notice him and Jeff is on risers behind Richie but he sits low to his keys so again you don't really notice him. these guys are strictly there in support roles, they know it and play their roles, period. Jon does ackowledge them at the end of the show when he introduces the band and they do take the bow with them but throughout the show they are pretty invisible.
I don't care if they're visible on stage or not visible. Bobby and Jeff on tour will mean more of the same setlists, not a lot of improvisation and more automatic pilot.
