Women have described the 'degrading' experience of going to the toilet at the Stereophonics gig, as some were forced to urinate against fences and 'shield each other with their jumpers' as they claimed there were not enough toilet facilities to cater for the masses.
Thousands of people packed into Swansea's Singleton Park to watch Kelly Jones' band put on a spectacular performance on stage .
The Cwmaman rockers performed all their hits to the delight of fans who turned up for the gig, which was 20 years on from their famous 1999 show at the old Morfa Stadium.
But whilst there were no complaints about the band's performance, many have arisen over the toilet facilities available to cater for the huge crowd.
There were said to be only 100 portable loos at the gig, which many felt was a tiny fraction to cater for the 35,000 people in attendance.
Swansea Council said the number of toilets was correct for the size of the audience.
But people at the gig claimed the situation was a problem particularly for women, as men were able to make use of open urinals in the park.
One woman who went to the gig said she had to wait an estimated 45 minutes in a queue, and was then directed to the disabled toilets, of which there were only six, and where she had to wait a further 20 minutes.
The woman, who asked not to be named, said: "There must have been about 50 men peeing against the railings, which didn't really surprise me, but what did was seeing girls, who were clearly desperate to go to the toilet, doing it as well against the fences.
"There were quite a lot of kids there and it would have been quite horrible for them to see so many fully grown women having to crouch down. Men were walking past and laughing and taking pictures. It was awful."
She added that a number of fights also broke out at the gig.
"Near the end of the gig a massive fight broke out right in front of us, and there was no security or police to be seen," she claimed.
"One guy in front of us was covered in blood. It was really poor from that point of view. It is a real shame as we don't get a lot of things here."

Many have also taken to social media to air their grievances.
Rhian Lewis tweeted: "Stereophonics were amazing. Horrendous infrastructure for the gig though. Nowhere near enough toilets for an event of that size, without any crowd management. Women having to shield each other with jumpers so we could pee. Degrading experience."
Andrew Davies tweeted: "Thankfully, the Stereophonics gig at Singleton Park has confirmed my hate of outside shows, miles of queues for toilets and beer, captive audience, money making machine."
And Louise Trowbridge wrote: "Will think twice about going to see a gig in Singleton Park. Toilet situation was absolutely disgusting, nowhere near enough for the amount of people in the park and being ripped off because of ridiculously overpriced drinks. Such a disappointment!"
A joint statement from the event organisers and Swansea Council read: "The Stereophonics event was an outstanding success for the city. This was the first time Singleton Park had hosted an event of this scale and demonstrated that Swansea, on the back of last year’s successful Biggest Weekend, has proven itself capable of hosting these large-scale, iconic concerts.
"There are a standard set of industry guidelines which concert producers follow when designing a site and the number of toilets provided for Saturday’s event was correct for the size of audience based on those guidelines.
"As with all major events such as football and rugby matches and music festivals, there may inevitably be some queues for toilets, but this is to be expected when you have tens of thousands of fans enjoying themselves in a contained event space.
"As with any event, we’ll review all aspects and, where improvements can be made, we will do so."
South Wales Police has been asked to comment.
