Is there some confusion here. Werner Richard Heymann did indeed write a song called "Das is die Liebe der Matrosen" (you can hear it at https://www.youtube.com/watch?v=MNR4QkqBZEs).
But Landsberg recorded the familiar old "The Sailor's Hornpipe."
It is the same music as on the Odeon record. It does include a couple of short quotes from the Sailor's Hornpipe but mostly seems to be original music.
