Mud, arrests and a dramatic no-show - it was every bit as rock and roll as a music festival should be.

At the biggest T in the Park yet, more than 200,000 music fans enjoyed 11 stages of live music across three days, but inevitably it was the spectacular weather which will be most memorable.

Yesterday, revellers turned from mud-brown to sunburnt-red thanks to a day of stunning sunshine - a fitting reward for the campers who had stuck it out through two grim, gungy nights.

The resulting euphoria was palpable at the main stage, where Paolo Nutini led the crowd in a sunny sing-along. Wellies were waving in the air as he broke into his feelgood hit New Shoes - which perfectly summed up the uplift in mood across the weekend. The flamboyant Scissor Sisters were another big name featured over the weekend.

Suspense was maintained to the very end as uncertainty surrounded the appearance of headline act Snow Patrol's keyboard player Tom Simpson. However, despite the small matter of his brief detention by police in Middlesex on Saturday, he was expected to make it on stage for last night's performance.

He had been arrested in connection with a failed court appearance in Glasgow. Strathclyde Police said a 35-year-old man had been due to be transferred to their custody from Uxbridge Police Station, but was later released.

Among those looking on was Alasdair Currie, 28, from Glasgow, enjoying his 10th T in the Park in a row.

To mark the occasion, he was wearing a customised T-shirt, with a memorabe slogan from the very first year's TV coverage: "D'ye ken the wans I feel sorry fur? The wans who urnae here."

He said: "This year has been a microcosm of all the other festivals - I've been muddy and I've been sunburned. But the one thing that's remained the same is the festival spirit.

"The camaraderie on the campsite is really incredible. I ran out of booze and food on the very first night, but I've never gone short - everyone helps each other out. A guy even gave up his Pot Noodle for me.

"It's the same every year - come mud, come rain, we just get on with it. On the way here I got stuck in a traffic jam and had to walk five miles, but you won't hear me complaining."

Meanwhile, attending her very first festival was Linda Caine, 55, from Falkirk, and her friend Janice Holden.

Mrs Holden said: "Our tents are pitched in two feet of mud, but it hasn't spoiled it one bit. Our husbands are waiting to hose us down when we get home."

As ever, the crowd were adorned with extravagant outfits, from Superman to Cinderella.

Sam MacKay, 25, and Kerry-Ann McCrum, 25, from Glasgow, were resplendent in ballgowns which they had bought onsite for £5 at an Oxfam charity shop.

"I'm going for the Julie Andrews look - you can call me the Queen of the Hills," said Sam, wearing a long flowing milk-white gown, to complement her wellies.

Earlier, singer Amy Winehouse, was the talk of the festival for all the wrong reasons after she pulled out of her slot, claiming to be suffering from "exhaustion".

Organiser Geoff Ellis said: "We just hope she can take a bit of rest and get back to her best."

Off stage, there were no major incidents, with Tayside Police saying that they had arrested only 50 people across the festival weekend.

Chief Supt Matt Hamilton, the officer in charge of policing the event, said: "There is a really good mood in the main arena and arrest figures are incredibly low considering the amount of people on site and we're happy with the way things are going."

Ambulance services said that there had been "no major cause for concern". In all, 470 people were attended to at the hospital tent and 32 were transferred to NHS hospitals for further assessment.

Ian Golding, head of Ambulance Services, said: "On the whole, people are presenting with hayfever, sunburn and other minor ailments and we have found that the general mood of fans has made this one of the most positive festival events to date."

The biggest headache for organisers was the traffic, although the improved weather also meant the car parks at the site were dried out and fully reopened after heavy rain had earlier left the area a swamp. The closure had contributed to a chaotic seven-mile traffic jam, which left some fans forced to walk the remaining miles to the campsite.

Police said there were no traffic problems in the area yesterday. However, some fans had decided they would leave early and miss the headline acts, rather than risk being stuck in another jam.
