American Singer Patti Page, who sold more than 100 million records during her seven-decade-long career, has died. She was 85 years old.

The Oklahoma-born Page was a major star and the premier female popular singer in the pre-rock 'n roll era of the early 1950s. Her best selling recordings of “The Tennessee Waltz” and “How Much Is That Doggie in the Window” were standards, and appealed to fans of pop tunes as well as those of country music.

She also was a pioneer in the recording technique known as overdubbing, in which she sang along with recordings of her own voice being played back.

In addition, Page hosted television variety shows and appeared in films.

She was scheduled to appear at next month's Grammy Awards ceremony in Los Angeles to receive a lifetime achievement award.
