Calum Scott, Simon Cowell's golden buzzer, may not have won Britain's Got Talent, he deserves to be called a winner with that kind of vocal talent. He's a cross between Ronan Keating and Sting. Nasal vocals do not usually sound good. There are very few who sound exceptionally good. Ronan Keating's voice is a good example. Calum Scott could come second. Diamonds may have been a wrong song choice for Calum during the finals of BGT. He lost to a dog.
