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.
