Two more musical acts have been announced for Hampton Court Palace festival, along with its new official dates since being rescheduled for August.

World renowned singer-songwriter Van Morrison will open the show on Friday 13 August, and alternative-rock group Keane will take the Thursday 19 August slot.

Tickets for both artists go on sale tomorrow from 10am on the show's website

Van Morrison and Keane join other headliners Tom Jones, Bastille Reorchestrated and ABBA parody group Bjorn Again at the festival.

Bjorn Again will play on August 14, Bastile Reorchestrated on August 17 and 18 and Tom Jones will close the festival on August 23 and 24.

Organisers decided to move the annual festival from June to August 2021 after the government announced its roadmap out of lockdown.

The festival has told ticket-holders they are entitled to a full refund if they can't make the new dates.

They added that those with tickets to shows transferred to 2022 will be offered an exclusive pre-sale opportunity for the new artists joining this year's line-up.

Artists who were announced for 2021 but will instead be playing the 2022 show include Lionel Richie, Rick Astley & George Benson.

Tickets for Tom Jones and Bastille Reorchestrated are already sold out for both dates they are playing at this year's festival.

But VIP tickets are still available and fans can also go on a waiting list.
