Irish boyband Westlife have also confirmed that they will be the headline act for the Sandown Park Music Nights extravaganza on 5 August.
Both of the bands will be providing entertainment to guests after a full days racing programme.
"Spandau Ballet is a legendary British band and we are delighted to welcome them to Sandown Park as part of their Reformation Tour. Our Music Nights have proved hugely popular amongst our racegoers over the last few years," said Sandown Park Racecourse managing director David Mackinnon.
