The pop band, who were among the biggest stars of the 1980s, buried the hatchet to play for 25,000 people at a concert to mark the Eurovision Song Contest in their home city, Liverpool.
BBC reports they decided against playing their three UK number ones - Relax, Two Tribes and The Power of Love. Instead, they opted for Welcome To the Pleasuredome, a number two hit in 1985.
When its rumbling rhythm and chanted lyrics kicked in, the band succeeded in rolling back the years.
