Middle-aged disco lovers in Japan boogie to the sounds of a past era, when flares, platform shoes and gold medallions were cool and the economy was on the upswing.

The disco boom of the '70s and '80s is enjoying a revival of sorts among older club- goers seeking an alternative to the hip-hop, techno and trance that dominate the current nightclub scene.

"Disco is so nice," said a 42-year-old disco-goer decked out in a white suit. "When I hear this kind of music, I can feel that my body remembers those days so well."
