He hosted London radio station XFM"s specialist show The Remix for 15 years. Before joining XFM, Temple-Morris was the main presenter on the Music Television show Up for lieutenant Live, presented shows for Atlantic 252 & British Broadcasting Corporation Hereford & Worcester, co-presented the Pepsi Chart on Five, and Takeover television on Channel 4. He hosted The Remix on Friday nights from 10pm till 2am.
The strapline for the show is "where dance rocks", and includes dance remixes of indie and rock hits, plus up and coming dance music of the dance rock crossover variety.
Most weeks there is also a 30-minute mix from a guest DJ, producer or artist called the "Superchunk" and now "The All Time Top 10" where remixers create a 10-minute mix featuring the artist"s favourite songs, this has become a competition with mixes featuring over 200 songs. The show, which was co-presented/produced by James Hyman (1999–2003) popularised the mashup genre, with a section called Bedroom Bedlam dedicated to unofficial bootleg remixes.
Many established names in the mash up scene, including Go Home Productions, Freelance Hellraiser, Loo and Placido and Osymyso, got some of their earliest plays on the Remix Show. Also, Kasabian, 2ManyDJs, Simian Mobile Disco, Reverend And The Makers, Infadels, Plan B, Fenech Soler, Killaflaw and Justice received their first ever air play on the show.
His last show aired on 4 September 2015.
Eddy regularly DJs at rock, electro and indie crossover nights around the United Kingdom and Europe and has supported The Prodigy, Pendulum and Delays on their United Kingdom tours. His own night, The Remix All Nighter, a spin-off from the radio show, took place at London super-nightclub, Matter.
