Bote - these are not internal comms, and they aren't NASA Select. They are "operational" comms on the ground at KSC, click on the "more info" button on the feed and/or head to the Database and you'll see what it covers.
Ehh, I wouldn't be so sure yet... The last night launch everyone said "won't be seen again" and delays put 130's launch from a daytime one to nighttime one. That is still easily possible for future missions.
