IT'S 22 years since blue-eyed, mad-maned teenager Lorraine McIntosh took the train from Ayrshire to Glasgow and caught the attention of English teacher Ricky Ross.

It was 1985 and the musical pair, with James Prime, Dougie Vipond, Graeme Kelling and Ewen Vernal, went on to form what was to become one of Scotland's most successful bands - Deacon Blue.

Five studio albums, six million album sales, and 18 top 40 singles later, the band are about to kick off their UK tour - the one which could bring the curtain down on a dramatic career.

There have been many break-ups and reformations, critical acclaim and stinging criticism, and the dreadful low of the untimely death of guitarist Graeme, who succumbed to pancreatic cancer in 2004.

In his final days Graeme was supported by Marie Curie Cancer Care, and his family and the rest of the band have become big supporters of the charity - getting behind the Evening Times Big Build campaign to create a state-of-the-art hospice in the city.

Now, with most of the band involved with interests outside of Deacon Blue, Lorraine thinks the shows at the Carling Academy on Friday and Saturday could be the last time they play together in Glasgow.

"We did our anniversary tour last year but this may be the last time we ever tour," she says. "We're all involved with other things."

These days Ricky is busy with his own solo career and writing songs for acts including James Blunt and Ronan Keating.

Dougie, who decided to quit the band back in 1994 to pursue a career in TV, is busier than ever, working with BBC Scotland's sports department.

James is still with the band - however Ewen is now pursuing his own musical interests.

And Lorraine has made a name for herself as an actress, appearing in River City. She is now preparing for a role in the new series of Taggart.

So before the city echoes to tunes such as Wages Day, Real Gone Kid, Chocolate Girl and Dignity for perhaps one last time, we have gone through our archives and dug out some classic Deacon Blue moments.

From taking an English class at a Lanarkshire school, to causing gridlock in the city centre as thousands of fans clamoured for tickets, to the ultimate high of playing to quarter of a million people on Glasgow Green, we take a look at the band's life through a lens.
