Thanks for the timeline. I bookmarked it. I was beginning to feel like an old fart (59), but me mum always listened to classical 78s. I passed it along to my son. I used to put headphones on his mum's belly so he could hear Mozart before he was born. Some of his first words were, "Choral Finale from the Ninth Symphony, by Beethoven, under the baton of Herbert VonKarion and the Berlin Philharmonic, Angel Records."
