I Like "Lily Marlene" & I like " The D-day dodgers" & to be honest I can"t be arsed about the authorship of the melody---at least ,two good songs will ensure its immortality. Of course, if you are a hard-up,LIVING,breathing musician who refuses to recognise the human frailty of his fellow men,then there could be a problem ahead !!Otherwise,life"s too short.Also,if writers of "pop" music use bits of say,Prokofiev, in their efforts to liven up their usual dross, at least it exposes many of the young people of today to music they might not otherwise have heard of.!! Which must be a GOOD THING !!
