My "English studies" have consisted mainly of watching the telly and listening to music, QM:)
Regarding the song, The Seekers sang it - and they're Australian - (my head's spinning now;-) as did Joan Baez and Pete Seeger, as a "protest song", but originally it's a black spiritual: I Shall Not Be Moved. Johnny Cash, Lonnie Donegan, Elvis Presley, Mavis Staples and many many others have sung it as such. Everton fans sing it as... erm... not sure if it's a protest song or a spiritual in their version, he he! The Housemartins do a rendering too. Anyhoo, seems to be a case of Cherchez l'Américain, as it usually is when things get confused (for me, not for you) and in this case early black American language usage.
I have a feeling I'll be referring back to this thread ... too much for me to remember at my age but it's very clear, QM, and I thank you. A very Happy Christmas to you and yours as well. Now shall we dance? Or worship. Or watch football. Or something >>
