Mic Christopher's 'Heyday' single is to be re-released on January 23 as a result of it soundtracking the latest Guinness TV and cinema commercial.

Says a Christopher family spokesperson: "People who weren't aware of Mic before are seeing it and going, 'That's great, where can I get the song?' Once they've heard the whole of 'Heyday', we're hoping they'll check out his Skylarkin' album which is still available."

The music for the €1.5 million Ireland-only Quarrel campaign was sourced by ex-Fat Lady Sings man Nick Kelly who's now gainfully employed by the Irish International advertising agency.

"We're delighted with the soundtrack on Quarrel," enthuses Guinness Marketing Controller Mark Ody. "It's a beautiful and uplifting song and suits the ad perfectly."

Filmed on location in Dublin, Clare and New York, the 60 second advert was directed by James Brown and stars Irish actor Michael Fassbender.

Mic Christopher passed away on November 29, 2001 after sustaining a head injury whilst on tour in Holland.

We'll have more on the 'Heyday' re-release and Mic's musical legacy in the first Hot Press of 2004, due in the shops on January 15.
