If you've never sang the chorus of 'I'm in the Mood for Dancing' in your entire life then, you have been doing it wrong, so go back and start over. The hit was brought to our airwaves back in the '70's from Irish girl group sensation The Nolans. These ladies stormed the charts all over the world with their catchy songs, even outselling The Beatles in Japan. They didn't even have Louis Walsh as their manager either! However, behind all the glitz and glam and their clean-cut image, there is a different story to be told. This documentary charts their success from the beginning, and the ups and down of their career and lives since then.
