This is interesting in that I think it becomes a licenced activity under the Licensing Act 2003 as Shedule 1, part 2, section 8 states:-

Use of television or radio receivers

8    The provision of any entertainment or entertainment facilities is not to be regarded as the provision of regulated entertainment for the purposes of this Act to the extent that it consists of the simultaneous reception and playing of a programme included in a programme service within the meaning of the Broadcasting Act 1990 (c. 42).

So, if they are playing recorded music or video, that must be regarded as a provision of regulated entertainment. Not many Wetherspoon pubs had juke-boxes etc to be able to claim 'Grandfathers rights'.
