Rory Hoy first appeared on Calendar when he made a film explaining what it's like to to have autism.
That was five years ago. Now the teenager, from North Yorkshire, is making a name for himself in the music industry.
The DJ and music producer has made a video with Ashley Slater, who was in a band with Fatboy Slim. In fact their band, Freak Power, had a number three single with "Turn On, Tune In, Cop Out".
The pair are now called Rory Hoy vs Kitten and the Hip - and their single is out now.
