The opera's composer Purcell died in 1695 from incurable T.B. aged 36, while in 1983 Klaus sadly died succumbing to complications due to Aids, aged 39. Both men were remarkably talented but died so young.
The Lyrics to this old aria are strangely prophetic. Watching it now, knowing what a difficult time Klaus was having, just adds to its intensity and sadness.
