Video report by ITV Anglia's Tanya Mercer.
If you look back 10 years, you might remember an unusual boyband that soared in the music charts.
The Choirboys were made up of by three young choristers who became an international sensation. Two of them came from Ely Cathedral.
The boys were chosen in a national talent competition and they became an international success. Their debut album sold 100,000 copies in the first week earning them a gold disc and they went on to receive two platinum discs selling 750,000 copies worldwide.
ITV Anglia got in touch with one of the boys CJ Porter-Thaw back to Ely Cathedral to find out what life was like back then and what he's up to now.
CJ watched the current choristers perform some of the music he once sang.
When he was this age, he was touring around the world, appearing on television programmes, making music videos and signing albums.
They were an instant success with their first single Tears in Heaven.
One of his highlights was going on Blue Peter to be presented with a gold disc.
CJ says it was surreal being a ten year old going on TV and singing with Andrew Lloyd Webber at the Royal Albert Hall.
Below shows a performance from the current choirboys of Ely Cathedral, who say CJ's fame put them on the map.
