A couple of years ago we had the joy of the presence of Katherine Whyte in the English Service. She was singing Jepthah's daughter at the opera house. We looked for recordings of her on Youtube and found an entire Parsifal where she's a flower-maiden. FOUR AND A HALF HOURS it lasts.
FOUR AND A HALF HOURS.
