While recording the Song Books and the occasional studio album, Fitzgerald toured 40 to 45 weeks per year in the United States and internationally, under the tutelage of Norman Granz. Granz helped solidify her position as one of the leading live jazz performers. In 1961 Fitzgerald bought a house in the Klampenborg district of Copenhagen, Denmark, after she began a relationship with a Danish man. Though the relationship ended after a year, Fitzgerald regularly returned to Denmark over the next three years and even considered buying a jazz club there. The house was sold in 1963, and Fitzgerald permanently returned to the United States.
