The Nolans are best-known for their song "I'm In the Mood for Dancing" and gained prominence as guest performers on numerous television shows in the United Kingdom in the 1980's. The majority of their charted singles and albums occurred in the early 1980's but they continued to be active until 2005 and were particularly successful in Japan.

After signing with CBS subsidiary Epic Records in 1979, the group enjoyed their greatest period of commercial success with seven UK top 20 hits between 1979 - 1982. Strong album sales followed their first TV advertised LP "20 Giant Hits" which reached no 3 in the UK charts in 1979.

In 1981 The Nolans won the Japanese Music Festival with their song 'Sexy Music', giving them their 3rd number one hit  single in Japan following 'I'm in the Mood for Dancing' and  'Gotta Pull Myself Together'.

The Nolans continued to appear on major Television shows & toured all over the world with their amazing stage shows. They continued to remain particularly popular in the far east & in 1987 they signed a 6 album deal with Teichiku Records (Sony music). In 1991 they became the first Irish group to be awarded the 33rd Japan Record Awards Kikaku Sho for best foreign recording artists.

The line up changed many times over the decades as various sisters came & went before the group disbanded in 2005 when Maureen's acting career began to take off. Maureen was the only sister who never left the Nolans group. In 2009, The Nolans reunited for a sell-out UK tour (promoted by Universal Pictures) to coincide with the 30th Anniversary of 'I'm in the Mood for Dancing".
