Pop band Wet Wet Wet have decided to re-form after a break of seven years, to tour and release new material.
Clark, Mitchell, Pellow and Cunningham will embark on an 11-date tour
The band sold more than 15 million records between 1987 and 1997, but split after singer Marti Pellow became addicted to heroin.
They will release a single and a new greatest hits album before embarking on an 11-date arena tour in December.
"The enthusiasm and energy and passion we had when we were 17-year-old boys is still there," Pellow, 38, said.
The Scottish band - featuring Pellow, Graeme Clark, Tommy Cunningham and Neil Mitchell - had number one hits with Goodnight Girl and covers of With A Little Help From My Friends and Love Is All Around.
Their break-up was so bitter that the band did not speak to each other for five years, until they were reunited at the funeral of Pellow's mother.
In the meantime Pellow has spent time in a rehabilitation clinic, had two solo UK hits and appeared in the musical Chicago in London and on Broadway.
Drummer Cunningham said: "You can't underestimate how much it has taken for us to get back together.
"But there's a lot of unfinished business and I still feel we didn't get to the point where we achieved all we could have achieved."
