But UTW, that would mean that Timothy knows something about the Eagles activities that the fans don't know about - absurd!

No seriously, wouldn't even have to be private shows - the concerts are booked six months to a year in advance, especially in arenas that have basketball and hockey. I worked in an NHL arena for years. The acts book months and months out - has nothing to do with when it is announced and tix go on sale. Entirely plausible they had booked some dates for 2016.
