Nell8 I'm rather ashamed to admit that it was Sandy McPherson at the organ (not sure about the spelling). I can't remember what I had for breakfast, some days, but the name popped into my head as soon as I read your post.
I was born in 1939, so my childhood memories are of Workers' Playtime, Vera Lynn's Forces' Favourites, The Billy Cotton Band Show (Wakey...wakey!) I could probably still remember the words and music for most of the wartime songs, because we only had 'the wireless' to listen to. My parents weren't classical music fans, so I didn't even know that such a thing existed.
I was taken to a performance of "Merrie England" just after the war, and was absolutely blown away by the sound of all those voices singing in harmony. It triggered a love of choral singing which I still maintain, though my voice is getting a bit past it now. I love most music, but some of the modern rap leaves me cold.
