I have a copy of 'Sing and Stay Human' right here. Angela sent it to me, unsolicited, in the 1980s after I'd expressed and interest in one of the songs she had sung when I'd played at at Chipping Sodbury folk club the week before. I still sing the song - 'T'Aad Man', which I render without the Furness dialect as 'Old Man' - to this day.

The songs are:

As Falls the Rose
Human Harmony
No Man's Better
Come All Ye Bold British Folksingers
Glowing Guitar
Independent Lover
Betsy's Prayer
T'Aad Man
Happy Return
We the Unmated
The Flyting of Life and Death
Bleakest Top
First of May
In Praise of Cooks
Pleasure and Joy
Not Without Dreams
Amongst Those Present
Fiddledee!

I don't see your Spanish Civil War song there, unfortunately, though that does sound like her in the clip. By the way, the concertina, as I remember it, was an English, not an Anglo.

Angela was indeed a remarkable woman.
