Swedish singer Marie Fredriksson, one half of Roxette, has been advised by her doctors to stop touring – which means their Greenwich Music Time date on July 8 is now cancelled.

The duet had been touring the world with a 30th anniversary show but that now stops, meaning their last ever performance was in Cape Town in February.

Marie and Per Gessle formed Roxette in 1986 and three years late became an international sensation with hit single The Look. Roxette went on to perform more 500 shows and sold 75 million albums.

Greenwich Music Time, at the Old Royal Naval College , will announce a replacement headliner for the Friday slot in due course. The remaining concerts in the series are 2Cellos on Tuesday July 5, Seal on Wednesday 6, Joe Bonamassa on Thursday 7, 10cc on Saturday 9 and Jamie Cullum on Sunday 10.

Marie, who suffered a brain tumour in 2002, said: “I feel nothing but joy and happiness when I look back on the Roxette world tours.

10cc are also set to headline a night during the concert series

“I’m particularly proud and grateful for coming back in 2009 after my severe illness and to have been able to take Roxette around the globe a couple of more times.

“Sadly, now my touring days are over and I want to take this opportunity to thank our wonderful fans who have followed us on our journey.”

Per said: “Who would have thought this tiny small town band from the West Coast of Sweden were to be still on the loose after 30 years. We’ve done mind-blowing gigs all over the world that has taken us far beyond our wildest and craziest dreams.

“I want to thank the mighty Marie, the Amazon of the holy voice, the Goddess of superb rock performance, the liberated and magnificent interpreter of my humble words and music, for this magic carpet ride.

“My God, what a great view we’ve had. The joyride on the road is over now – but we sure had fun, didn’t we?”
