Input: Consider Input: Question: How long had A&M Records been in business at the time the Carpenters signed a contract with them? Passage:The siblings were born in New Haven, Connecticut, and moved to Downey, California, in 1963. Richard took piano lessons as a child, progressing to California State University, Long Beach, while Karen learned the drums. They first performed together as a duo in 1965 and formed the jazz-oriented Richard Carpenter Trio followed by the middle-of-the-road group Spectrum. Signing as Carpenters to A&M Records in 1969, they achieved major success the following year with the hit singles "(They Long to Be) Close to You" and "We've Only Just Begun". Subsequently, the duo's brand of melodic pop produced a record-breaking run of hit recordings on the American Top 40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary music genres. The Carpenters had three number-one singles and five number-two singles on the Billboard Hot 100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90 million records worldwide, making them one of the best-selling music artists of all time. The duo toured continually during the 1970s, which put them under increased strain; Richard took a year off in 1979 after he had become addicted to Quaaludes, while Karen suffered from anorexia nervosa.
