PBS has a streaming thingy for most of their programs, but I don't do the streaming things, so have no use for it.
I too grew up with LIVE FROM THE MET and have VERY fond memories of listening to it with my grandparents and mother, and the also my father, when WW II ended and he came home.
For fun and giggles ( as a hobby ), my grandfather was a "SUPER" at the Met and also a few other opera houses, so along with a lot of other kinds of music that was played, sung, and listened to, in my home, I had quite the extensive music education before I ever went to school.
Our music was broad in our family growing up and we went to NYC occasionally, more often to the BushneLL. I homeschooled the children and tried to give them a similar broad scope in Music. I provided American Songbook, medievil classical of all kinds, musicals, crooners, serious singers, and fifities and sixties music, while their father helped them become familiar with seventies and up to current music.
My son is the only black country western music fan I know.
