Christmas at Belmont question

I thought CAB was pre-recorded and broadcast on PBS during the season. Does anyone know if they are doing it differently this year? On their website, it says that the CAB2017 show will be rebroadcast this year. Any idea why?

The Christmas at Belmont concert is held every year, but it is only recorded for TV every other year. The recording years features a guest host and it is held downtown and not on campus. During the Off years, reruns are shown from the previous years.

Thank you! That makes sense now. They didn’t mention that fact on the tour! lol
