Tourists visiting Covent Garden can expect to see living statues, hordes of stag and hen parties and the usual stalls selling "My boyfriend went to London …" T-shirts (a bargain at just £25 and guaranteed to last a week) – but recent visitors may have been lucky enough to spot Tom Jones busking. The Voice coach took his semi-finalists, Sally Barker and Bizzi Dixon, down to the London spot to give them a lesson in performing to a crowd and even belted out It's Not Unusual and Kiss for passers-by. The Sun reports an 'insider' as saying: "He brought Covent Garden to a standstill," which as anyone who's visited the place on a Saturday would know, isn't that unusual at all.
