In 2002, Colin was headhunted to front Channel 4's ill-fated breakfast show RI:SE but left to front the channel's late-night music shows. In late 2003, he was reunited with RI:SE co-host Edith Bowman for The Colin and Edith Show, which pulled in more than five million listeners before the pair went their seperate ways in 2006. Since then, he has presented Five's American football show, NFL Live, and the channel's European Poker Tour Series. He currently presents the channel's coverage of the UEFA Cup and hosts the topical sports-based news show Fighting Talk on BBC Radio Five Live. However, he hasn't forgotten his roots and also presents a late-night weekend show on Radio Ulster.
