The main plus for the LMB - is that it has removed the licensing requirement for Entertainment Facilities. So no longer is the supply of the piano itself licensable.
George Orwell may not approve. I wonder how he would view Karaoke?
The only real problem is that the requirement for additional entertainment licensing permission will automatically kick-in at 11pm - and now in venues which very often open and can serve alcohol until much later.
We can always console ourselves at 11pm by playing darts/pool - as these will not require additional entertainment licensing permission, either before or after 11pm.
