Tickets for a once-popular concert are being given away for next to nothing on a seat-filler website.

Three out of four shows at the Rochester Castle concerts next month are being sold at a cut price.

It means tickets for acts such as the Sugababes, Soft Cell and Fat Freddy’s Drop – which cost round £55 – have become available online for just a small £6.50 admin fee.

The revelation is the latest in a line of blows for the concerts, which have been marred by controversy and disappointment.

Last year’s event was criticised by VIP ticket holders who were unhappy with “warm wine, no food and dirty toilets”.

The upgraded ticket cost an extra £49 and was meant to bring a dedicated fast-track entry lane, private bars and food area, as well as access to premium toilets and VIP seating.

At the time concert-goer Ashley Pearson said: “We were promised a VIP food area. There wasn’t one. There was nothing at all serving food, you had to go into the main arena.

“There was only one bar, and it was serving the same as the main arena bar, it was the same menu. In fact, the VIP menu look tattier with bits covered up and changed.”

Before that, multiple cancellations left people with a long wait for a rescheduled event or refunds.

It was due to the Covid-19 pandemic and a delay in “freedom day” from then Prime Minister Boris Johnson.

In 2019, Jess Glynne became public enemy number one in the Towns after a late-cancellation of her performance at the last minute.

The Brit-Awards winner was the big draw that year, but left fans disappointed after having to pull out following advice from her doctors.

She said: “It absolutely kills me to say this — especially given what has happened in the past few weeks — but on the advice of my vocal surgeon, I am going to have to cancel my next few shows through until July 14 and I hope to be back as soon as possible after that.”

While the year before, Medway Council was forced to defend its decision to ban drinks at the 2018 concert.

The local authority said it made the decision to “ensure overall safety and enjoyment” for customers.

Concert organiser AGMP has been contacted for comment.
