Coldplay are to perform the second of two "secret" gigs on Monday to raise funds for homeless charity Crisis.
The band are playing in Newcastle on Monday following Sunday's Liverpool gig - the venues were kept secret until 24 hours before the band stepped on stage.
Liverpool's took place at the Royal Court Theatre and was being supported by the Choir With No Name, whose members include homeless people.
More than £238,000 has been raised for Crisis so far, the charity said.
"To have the backing of Coldplay brings something unique to Crisis this Christmas," said Leslie Morphy, the chief executive of the charity.
The Newcastle gig will take place at the city's Journal Tyne theatre.
Both venues were picked by Coldplay for their intimate nature and each has a capacity of about 1,000 people.
TV presenters Anthony McPartlin and Declan Donnelly have offered to compere the Newcastle gig.
