What country is the song "A Fire in the Winter" by Fei Xiang?

Fei Xiang's "A Fire in the Winter" is a cover of Sexy Music (Dancing Sister) by The Nolans, a purely family band that originated in Ireland and later settled in England. In the mid-70's mom Maureen and dad Tommy retired from the scene and the boys in the family were banned, forming a purely sister band. Sometimes a quartet, sometimes a quintet. They quickly became one of the best of a large number of disco dance groups that emerged in the mid-1970s. The Nolan sisters' Sexy Music (Dancing Sister) was a hit when the band visited Japan to perform.

Fei Xiang became popular at the '87 Spring Festival Gala with a song called "A Fire in the Winter," which was a cover of the Nolan sisters' Sexy Music.
