Hi Bald Eagle
I am pleased to say that I can ID the artist. It is Fiona Simpson who in the 70's performed in a duo called Therapy and had an album called "Bringing The House Down". She went on to perform solo around the British folk clubs and released a few albums, mainly doing covers of contemporary songs but also a few trad numbers.
The album you refer to is the only one I can't find at the moment! but I think it was called "This Is Where I Came In" - when I find it I'll let you know for sure. She released at least 2 others titled "Beneath The Rose" and "Still Time". She was great fun, a popular guest with a big personality - a beautiful person with a big, beautiful voice. She was based around the Manchester area.
Since 1993 she has concentrated on music with a strong Christian message and performing as the Fiona Simson Band she has a web site click here
Hope this all helps.
