Bernie, Coleen, Maureen and Linda have today announced details for their farewell tour, which will stop off in Glasgow at the Clyde Auditorium on March 13 next year.

Tickets for the final gigs go on-sale on Friday, and lead singer Bernie admits it'll be a mix of emotions as they get ready for a final fling.

"We did the last tour back in 2009 and there was a lot of demand, a lot of people saying: 'Oh, I want to bring all my friends'."

"We thought we'd do another but that it had to be the last tour - we want to go out on a high.

"We're all still performing and singing well and dancing well, and we want to do that to the best of our abilities."

A showbiz survivor who's enjoyed a lengthy acting and theatre career too, Bernie reckons that Glasgow crowds are right up there with the very best in the business, and always enjoys heading up this way.

"Glasgow has always been one of the best places to play as it's always been so appreciative and mad, just like us," she says, letting out a howl of laughter.

"All acts need and want that response from crowds, and you always get it in Glasgow.

"The Clyde Auditorium's a beautiful place to play and the crowd was amazing last time.

"They showed appreciation so much, and it's great to be doing it near the end of the tour.

"My husband did panto there years ago with Cannon & Ball and we were up for six weeks, so we stayed in an apartment and had a wonderful time.

"I feel an affinity with the Scots as they're so like the Irish.

"They're family orientated, they love life and they show their feelings."

While everything is going great for Bernie just now, there's often been a darker side to the family.

Bernie suffered the tragedy of a stillborn daughter in 1996, while in recent years three of the sisters have had breast cancer, although thankfully all have recovered.

"We're still here, touch wood, so we are survivors," reflects Bernie.

"We know we're lucky still to be doing it."

There are a lot fewer fallings out among the siblings now than in their 1970s pomp, when they were TV and chart fixtures.

"We fall out less because we're older now, and we don't see each other as much," Bernie chuckles.

"Familiarity breeds contempt, and we were together 24/7 for years back then. Now we miss each other because we're not together as much. So getting back together is just fun."

While having such success as teenager might have seemed a dream, there was a down side to the Nolans' fame.

They may have been hits with the public, but there were plenty of people out to knock them down a few pegs.

It's clear there was a real impact on Bernie when she found out just how harsh people could be.

"One newspaper came out and did a day in the life of the Nolans, where our mum made them breakfast, lunch, dinner.

"We all a great laugh - then the headline was Queens of Naff," she says.

"That was really annoying, but I've toughened up now.

"At the time we were so naïve and so nice, and I'd never do that again."

Being stitched up wasn't the only problem, either.

The sisters were often faced with sexism during their career, something Bernie feels still goes on in the pop and showbiz world today.

"It's always tougher for female acts," she explains.

"I'm a bit of a feminist, although not in an annoying way, but you can't deny it's a man's world and things like the casting couch are still going on.

"The way you're judged on what you wear, how you look - it's harder and there's extra pressure on girl groups."

But Bernie's a big fan of one modern girl band, in particular.

"Little Mix are really good," she says,

"They seemed to sing really well on the X Factor and good luck to them."

However she's not ready to give up the stage to the younger generation just yet, and thinks next year's shows will see the sisters go out on a high.

"We've got the boy dancers again, some lovely sets and costumes," she adds.

"It's going to be great.

"Fans know they can come along, have a good time and that they'll be dancing in the aisles.

"That's what we want."
