Eldo di Lazzaro, in German: Hildo von Lazarus.
(* February 1902 in Trivento, province of Campobasso; † 1968 in Genoa) was an Italian singer and composer of light music and film music.
In 1939, he published the hit song ''Reginella campagnola'', which became so successful that it became the basis of the Heimatfilm ''Am Abend auf der Heide'', produced in 1941 Germany by director Jürgen von Alten. In the USA, the song was simultaneously known as ''The Woodpecker Song'' and was sung and recorded, among others, during the war in 1940 by Kate Smith accompanied by The Andrews Sisters and the Glenn Miller Orchestra. Other performers included Tino Rossi, Rudi Schuricke, Glenn Miller, Will Glahé, Ernst Mosch, Frank Sinatra, the Everly Brothers and others.
