Aled had a sublimely beautiful treble voice but if you want to explore boy trebles who were very famous in their time years before Aled came along, I recommend listening to Derek Barsham, Billy Neely and Graham Payne to name just three.
Aled was not nearly the first famous boy soprano. Back in 50-60's, an Italian miracle boy by the name Robertino Loreti has taken the post-war Europe by the storm. He started as a restaurant singer, but was very quickly catapulted into international fame by a Danish producer who noticed him while vacationing in Rome. Robertino was insanely famous and popular, at the time when my parents just started dating his songs blared from every radio. I think, he's still alive, and his performances should be available here.
A massive thank you for your so appropriate analysis of soprano boys voices so we can really appreciate those amazing and melodious voices. Have you heard soprono Aksel Rykkvin ? All you said about Cormac Thompson and Aled Jones is applicable to this singer who is now a baritone singer since a few years ! I would like to have your opinion about him. Thank you in advance .
