at the same time "sailor" rode the u.s. charts, the german melodies "wonderland by night" and "calcutta" were becoming number one hits in instrumental versions by bert kaempfert and lawrence welk respectively, with "wonderland..." also reaching the top 20 in an english-language vocal version by anita bryant. later in 1961, joe dowell had a number one hit with his cover of presley's take on the german folk song "muss i denn" titled "wooden heart", sung partially in german. a spate of other german-language 45s by other artists such as willy millowitsch, heidi bruehl, and marlene stolz, were also issued in the united states, although none of these were successful.
