I remember "We'll meet again" as a very sentimental Vera Lynn
Second World War song and was still sung when I was in the Royal Navy in the 1950's and 1960's. I am sure it was sung to us in the hangar of H.M.S. Victorious very kindly by Anne Shelton, another WW II sweetheart of the forces, on the occasion of her visit to us sometime around January 1967 in Hong Kong. The version that I now sing can be found in 101 Pub Favourites for Buskers
where the words and musc are credited to Ross Parker
and Charlie Hughes.
