ABBA fans have said they are “shaking” with anticipation as the group prepares to make a big announcement.
The Swedish stars are set to share some big news on Thursday, with members Björn Ulvaeus and Benny Andersson pictured arriving in London ahead of the big reveal.
Fans are convinced it is going to be a tour or some new music after 39 years – or both. There are also rumours it could be a "hologram tour" that was first touted a few years ago.
ABBA – which includes Agnetha Faltskog and Anni-Frid Lyngstad – formed in 1972 and was known for songs such as Waterloo, The Winner Takes It All and Dancing Queen.
They last performed together with the original line-up in 1982.
Then last week a Twitter account called ABBA Voyage popped up with a date – 02.09.21.
Billboards with the same date also started appearing around London and a couple of days later a message posted on the Twitter page said: “Thank you for waiting, the journey is about to begin.
"Agnetha, Björn, Benny, Anni-Frid.”
“To all the fans around the world...we are so excited to share the future of @ABBA with you today,” said another tweet on Thursday morning.
“See you at 5:45pm (UK time).
"The journey is about to begin.”
Fans have been struggling to contain their excitement ever since.
“I’ve never been so ready yet so unprepared for something in my entire life - I’m shaking,” said one.
Another said they were “refreshing the link every few minutes filled with sheer excitement”, and one fan said they had “a stomach full of mad butterflies”.
“So this is what people must have felt, waiting for the Moon landing in 69,” tweeted another fan.
One person shared a picture of a ticket from an ABBA concert in 1979, and said: “42 years ago was the happiest day in my life. Tomorrow just may be the second!”
“If ABBA do a reunion UK tour I’m willing to part with thousands,” posted another excited fan.
One said: “39 years since The Visitors & ABBA are finally releasing new music. I’ve only been alive 20 years but I can still confidently say I’ve been waiting my entire life for this. I grew up with this band & can proudly say they changed my life. I am READY.”
ABBA are set to make their announcement at 5.45pm on Thursday.
