Thornton's success with "Hound Dog" was followed three years later by Elvis Presley recording his hit version of the song. His recording at first annoyed Leiber who wrote, "I have no idea what that rabbit business is all about. The song is not about a dog, it's about a man, a freeloading gigolo." But Elvis' version sold ten million copies, so today few fans know that "Hound Dog" began as "an anthem of black female power." Similarly, Thornton originally recorded her song "Ball 'n' Chain" for Bay-Tone Records in the early 1960s, "and though the label chose not to release the song... they did hold on to the copyright"—which meant that Thornton missed out on the publishing royalties when Janis Joplin recorded the song later in the decade. However, in a 1972 interview, Thornton acknowledged giving Joplin permission to record the song and receiving royalty payments from its sales.
