My mother's mother could just remember Queen Victoria dying - at least when all the shop windows had black cloth and pictures of the queen instead of what they sold. She lived in the village of Fulford now a suburb of York, Yorkshire, England.
She used to sing Bird in a Gilded Cage, and she was a good mimic - I have heard recordings of music hall artists and sometimes the familiarity makes my hair stand on end. Even songs sung by men, the phrasing and vocal mannerisms are recognisable.
I'm afraid I did not make notes - assuming I can always go back and find them again, but the 'on stage' pronunciation would seem to be guil - dered cayge in her rendition of the song, with emphasis on cage. Nanna would always lift her hand to her cheek at the words ''Tis sad when you think' in the chorus - as though to wipe away a theatrical tear.
This would be overacting today of course, but would probably date to music hall performances before the Great War.
