In 1977, Houston was signed by Private Stock Records, working with arranger/producer Michael Zager on three albums. The second included her big disco hit "Think It Over", which climbed to No. 32 on the Billboard R&B chart in 1979. She represented USA at the World Popular Song Festival in 1979 with a track called "You're the Fire", landing second place and winning the "Most Outstanding Performance Award". This also appeared on her 1980 disco-flavored album, "Step Aside for a Lady", again produced by Zager, but released on Columbia Records (on EMI in the United Kingdom).
