[Steve in Pudsey]

I noticed that Late Night Lycett has what looks like a special opening when seen on demand, in which Joe predictably calls the service by it's old name

I think it's sufficiently distant from first transmission that I can explain why - the on demand version has content the broadcast version did not, subtly pointed to via the QR codes displayed around the set. The on demand version just admits it outright rather than relying on the gimmick, but I appreciate the effort to try to make some interest in catchup for a show that would otherwise be a real live event only.
Whether that will continue for the whole series I don't know, but it'd be interesting to see if it did lead to a viewership spike.
