Catriona Stewart's verdict: four stars
Deacon Blue give it what can only politely be described as laldy.
The four-piece are continuing a slight vintage trend begun on Friday with The Proclaimers and continued with Texas and Kraftwerk.
Ricky Ross, lead singer, is the George Clooney of Scottish pop; despite getting on in years, you'd still totally give him the eye.
He is slick and personable and knows absolutely what he is about with this festival crowd, who are eager and willing to lap up some sunshine tunes to dance to.
And sunshine tunes to dance to are precisely what Deacon Blue deliver. Age aside, everyone knows the lyrics to the band's classic, classy pop numbers: Loaded, Real Gone Kid, Wages Day, Twist and Shout.
Ross works the stage, in equal parts modest and flattering - implying it's an honour to be here, making the crowd feel they're the best on earth.
He suggests anyone of faint disposition leave the arena as things are about to get faster, harder and louder. Well, they do and they don't.
But fun, certainly, is what they get. Fun, lively and festival pitch-perfect, particularly with Fergus Sings the Blues and a belting closer - Dignity.
One sticking point only is Lorraine McIntosh's vocals, which sound slightly shrill, perhaps due to feedback, perhaps her microphone.
Ricky, at set's close, says: "You have made some old men and women very happy."
Thanks, Ricky, but you've made thousands more very happy in return.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
