Bjorn Again will play at Vale Castle to celebrate the Queen's 91st birthday

Two special outdoor concerts will take place at Vale Castle in Guernsey, to celebrate the Queen's 91st 'official' birthday. And the world's No.1 ABBA tribute band, Bjorn Again, will be playing!

The tribute band will be encouraging people to dress in 70s and 80s outfits, to fully embrace the ABBA spirit of the night.

Bjorn Again originally began as a parody of ABBA, but have been growing in success over the years, even gaining praise from Björn Ulvaeus and Benny Andersson themselves.

Björn and Benny were quoted as saying in 1999: "BJÖRN AGAIN are the closest you can get to seeing ABBA. ABBA will never reform!"

The tribute band's performances at Vale Castle follow the Killer Queen concerts held last year, for the Queen's 90th official birthday.

The Head of Marketing and Events told ITV that the 'historical' site is a 'stunning' venue for an outdoor summer concert.

The gigs will take place on 17th and 18th June at 7.30pm. Get your tickets here!
