Poopsie, back in the 60s (in Australia anyway) before the records of the Kingdom songs first came out, the Society allowed classical music to be played at intermissions of the assemblies. But I never heard of classical music being allowed in the KHalls, though.
In the 70s, I remember we had a piano and someone used to play the Kingdom songs on it. When the recorded music came out I missed the sound of live music.
I didn't mind some of the music, as I loved music for music's sake. Even as a JW I liked gospel songs too, lol.
I'm glad I wasn't around to hear the killing of the songs with the latest songbook. I'm yet to hear anything positive about the new songs.
