In 1948 he returned to the Netherlands as an American citizen to search for news about his family. Upon his arrival, in gratitude for his wartime broadcasts, thousands of people greeted him and he was offered a contract to sing at the largest theatre in Amsterdam. Not having sung for over five years he was petrified with fear, but was such a success that he was held over for six weeks. Having regained his confidence, he accepted an engagement at the London Casino where he was a tremendous hit.
