Auf Wiederseh'n Sweetheart by Vera Lynn
I've never heard or heard of the song before.
"Auf Wiederseh'n, Sweetheart" is a popular song and a cover version of "Auf wiedersehen, auf wiedersehen" written by German composer Eberhard Storch[when?]. Storch wrote the song in the hospital for his wife Maria as he was ill for a long time.

The English language lyrics were written by John Turner and Geoffrey Parsons. The best-known version of the song was recorded by English singer Vera Lynn. The story goes that Vera was on holiday in Switzerland and heard people singing the song in beer parlours,[1] and when she got back she felt she had to record it, so found the music and had lyrics written.

I remember the Version by Rudi Schuricke quite well!
