"...Jane had started writing songs while still a student at Queen's University; her first was about a boozy Irish spinster she met while working as a chambermaid in London's Waldorf hotel.

"Later covered by Andy Irvine, Brigid was the catalyst for several commercial recordings by Jane including Waves of Time (Claddagh 1983), The Empty Road (Claddagh 1985) and Mary Ann McCracken 1770-1866 (Ashgrove Music), a tribute to the famous Belfast radical, featuring Maurice."
