Vera Lynn was a famous singer during the Second World War. Her most famous song was We’ll Meet Again. She is 98 and still singing.
I found another version,from a reader who is from Kentucky and has a great voice and is a well known mandolin player, at least well known around Louisville. She said the Johnny Cash version was recorded when his wife June Carter Cash was on her deathbed. It isn’t typical of Johnny Cash but a beautiful rendition of this old song. Listen for the great guitar accompianist in the background.
