Great Comet B-roll?

I have been watching the interviews that Great Comet has been posting on YouTube that were done with cast members during the recording of the album.

During these packages they have been showing a significant amount of video footage from the show - it looks like they perhaps filmed an entire performance with an audience in place to use for clips.

Does anybody know if the collection of these b-roll clips is available online anywhere to view?

This one also has some good footage, some of it the same as above, some new: https://www.youtube.com/watch?v=Q1No2U5kulA
