From the wiki:
In 1985, the trio joined up with Marc Almond to record a version of the Donna Summer classic “I Feel Love”. The full version was actually a medley, also incorporating snippets of Summer’s “Love to Love You Baby” and John Leyton’s “Johnny Remember Me”. It was a huge success, reaching #3 in the UK, equalling the chart achievement of “Smalltown Boy”. Although the original had been one of Marc Almond’s all-time favourite songs, he had never read the lyrics and thus incorrectly sang “What’ll it be, what’ll it be, you and me” instead of “Falling free, falling free, falling free”.
