Aha – I just found a review of the Bach Christmas Oratorio I sang in before Christmas – ‘sublime alto’ they call me. https://www.great-milton.co.uk/wp-content/uploads/2019/12/Dec-2019.pdf
Of course, I was far too concerned with my ‘Christmassy’ outfit (a glittery gown, no less) to get my Edirol out and record the darn thing. So I shall have to trust that my own feeling was of huge satisfaction to sing with such a great band, and lovely chorus, and what a glorious communal event. Let alone a sublime piece of music. Thank you Johann Sebastien.
