Delilah will sound out from between the domes of Greenwich's Old Royal Naval College as Sir Tom Jones comes to town.
The Welsh crooner will close the final night of Greenwich Music Time’s second concert series on July 26.
The 5,000 strong crowd expected at the World Heritage Site will be treated to a outdoor gig exclusive to the capital – coinciding with the star’s 50th anniversary in the music business.
Sir Tom said: “I’m really looking forward to performing at Greenwich Music Time this summer and it’s great to be sharing the bill alongside such an esteemed group of artists.
“The Old Royal Naval College is a beautiful place to do a show and I’m sure it’s going to be a really special occasion.”
GMT organiser Peter Taylor, of Cuffe and Taylor, said he was “over the moon” at the addition of The Voice coach to the line-up.
He said: “He’s celebrating 50 years in the business – that’s no mean feat. The show’s a celebration of that and it’s going to be all of his hits.
“It’s going to be a great atmosphere. Normally, he’s playing in Hyde Park to 50,000 but here there’s 5,000, so it’s a lot more intimate.
“And there’ll be people from 16 up to 80 because he’s got such a broad appeal.”
Opening the event on Thursday, July 23, will be the Gipsy Kings, followed by Kinks frontman Ray Davies and George Benson on Friday.
After the success of last year’s inaugural event, Peter said interest in 2015’s extravaganza had rocketed.
“After 2014 we were inundated with people approaching us and wanting to do the show. Normally, as a promoter, it’s you chasing the artists,” he said.
“We want to keep it fresh every year and, we some people that came last year enjoyed the venue as much as the artists too. It’s really special.”
