The Tenors coined 'Buckingham Palace house band'
A Canadian quartet who sing a mixture of pop and opera say they have been coined the "Buckingham house band" by the Duke of Edinburgh.
The Tenors - Victor Micallef, Clifton Murray, Fraser Walters and Remigio Pereira - told BBC Breakfast they have performed for the Queen and Prince Philip on four occasions.
The musicians are now hoping to break into the UK with their new album.
