Cliff Richard is too old
It's official. In two years' time, Cliff Richard will have officially outlived himself. Well, the stuff he made in 1958 anyway. That is unless the British government changes copyright law for sound recordings (they're not even called songs!) to protect the artist for his or her lifetime plus 70 years, much the same as written copyright is protected (such as, I don't know, the LYRICS of Cliff's songs?).
