Ake,
re your last two lines:

"As long as someone sings a song,
as long as someone listens,
as sure as summer follows spring
and sun will rise and set,
and even when we are long gone,
this story is never ending:
As long as someone sings a song
it isn't over yet".

i.e. I'm with the hopeful brigade. Live, participatory, non-star-system, unamplified music will live on; one way or another.
