The former director of an international folk festival is considering bringing an event to Carmarthenshire in 2006.
It is hoped that festival-goers will flock to the Llanelli site
But Steve Heap has denied speculation that it would mean moving the Sidmouth International Festival to Wales.
Mr Heap said although he had spoken to Carmarthenshire Council about a possible event in Llanelli, it would not be the one which had been held in Devon for 50 years.
The council plans to meet Mr Heap and has offered Llanelli's Festival Fields.
However, Mr Heap, who runs an events company, said he wanted to quash speculation that the Sidmouth Festival itself would be moving to Wales.
His company had organised it until 2004, but faced with escalating costs, had decided to make the 50th Sidmouth festival the last one under its management.
However, Mr Heap said it should stay in Devon.
"I can quite categorically state that the 50-year-old Sidmouth Festival belongs and should remain in Sidmouth," he said.
He added that his company ran a variety of events including folk, jazz and classical music. Until he saw the Llanelli site, he would not know what might be suitable there.
Carmarthenshire Council said if the Festival Fields site was suitable, Mr Heap's event could be staged there in August 2006.
More than £65,000 is being spent at the site on new infrastructure including a permanent fence and power.
It has already staged a number of events including a three day Party on the Coast extravaganza last summer.
Councillor Clive Scourfield said: "The Festival Fields is a fantastic site and is rightly attracting interest from far and wide.
"It is in a stunning location and the recent investment will provide the infrastructure needed to attract big name organisations.
"The council is committed to providing better events and entertainment across Carmarthenshire and we are confident that Festival Fields will become widely known as a major venue in Wales."
