The UK Musicians Union is pressing British broadcasters to institute an on-air system to notify viewers when a musical performance is being lip-synched, saying that such a system would encourage more bands to perform live. “Just as when you buy a can of beans and it tells you what’s in the beans, we think if you are going to buy a ticket for a show or watch a band on the TV, you should know exactly what it is you are buying and what you are watching.”
