Still nothing new ...

Any chance His Bobness is once again involved in Mark's fall schedule ?
Bob needs a lead guitarist for his Europe fall tour. We all know one guy who would kill to get the job

Easy conclusion.

That could explain why there's no confirmation so far - and no dates, no tickets ... - and why GF's answers suddenly changed.
Sorry my dear American friends, I'm only speculating, I don't want to ruin your dreams
You've probably heard that Krusty fired his guitarist in the middle of his american tour and called back Charlie Sexton to replace him on stage the day after (July 3rd). Rest of the month , Charlie played alternately with Colin Linden depending on their availability. My understanding is both of them were only an emergency solution and someone else will join Bob's band in Europe. A Krusty-compatible top guitarist who can boost up the sales...

So, if Bob called Mark early July, do you think he got a clear no as an answer ?
