Elton and his band will play a second headlining Eden Session concert next summer due to a huge demand for tickets.
Tickets sold out in just a few hours of general sale on Friday. So now a second concert has now been added, for the following evening.
The performer will now appear on Tuesday, June 16, and Wednesday, June 17.
Eden's Marketing Director Rita Broe said, "We've had an amazingly positive response to the news of Elton John returning to play in Cornwall for the first time in 30 years and appearing for the first time at Eden. The demand for tickets for the June 16 Session has been overwhelming.
"We are thrilled to announce that Elton can play a second Session on the following evening. We are certain his fans will be as delighted as we are at the prospect of double the number being able to see him perform. Two magical nights of Elton at Eden coming up!"
Tickets are on sale at 4 p.m. today.
