Dec and his best friend Ant tried to become pop stars as well. Their stage names were PJ and Duncan and they became really successful when they released their song, called ‘Let’s Get Ready to Rhumble’, which was actually nominated as ‘Best Song’ in 1994. But another song ‘Falling’ had to face some problems. One of the pop Welsh bands accused Dec and Ant in copyrighting and stealing their song. That’s how their singing career stopped.
