In the mid-1970s, Richard Carpenter developed an addiction to Quaaludes. The Carpenters frequently canceled tour dates, and they stopped touring altogether after their September 4, 1978, concert at the MGM Grand in Las Vegas. In 1980, Karen performed a medley of standards in a duet with Ella Fitzgerald on the Carpenters' television program "Music, Music, Music". In 1981, after release of the "Made in America" album (which turned out to be their last), the Carpenters returned to the stage and went on some promotional tours, including an appearance for the BBC program "Nationwide".
