S Club 7 bringing it all back
The band’s highly-anticipated comeback was one of the highlights of last night’s show and plenty of fans took to Twitter to share their excitement at seeing the S Club 7 performing together again - and they have plenty of celeb fans too.
Many S Club 7 fans are now hoping that the band will announce a full renunion tour.
The 'EastEnders' team also took part in the fundraising efforts, and Ian Beale took the lead role in one sketch, which saw him coming face-to-face with the ghosts from his past.
