Former Korn star Brian 'head' Welch is considering a full return to the band he walked away from in 2005 for a future North American tour.

The rocker, who quit the group to seek help for substance abuse issues, has become a born-again Christian - and he thinks a full reunion with his former bandmates would be a great message for fans.

He tells, "Everyone is broken in this world. There's so much divorce, hate and unforgiveness. For people to see this, I think it's just really uplifting. I never thought it would happen, and I'm not sure they did either. The fans just love it, because a lot of the fans back in the day were like, suicidal, and from broken homes and abuse.

"They looked up to us like their family. And to see their family split up was hard on them. To get it put back together, there is a joy around the people who care about it."

Welch joined the band onstage for one song at the Carolina Rebellion Festival last year (12), and now he's preparing for his first full set with Korn since 2004 at the Rock on the Range Festival in Columbus, Ohio in May (13).

The band will then head off on tour in Europe and the guitarist will tour with his band Love & Death, but he isn't ruling out future dates.

He says, "We're going slow. We're hanging out when I've got time, but I've got my album out, and they're busy doing their stuff. But I'd say anything is possible right now."
