Promises was formed, recorded and produced by Steve Verroca, who leased the group's album to EMI EAR Holland.
In February 1979, the soft rock[1] single "Baby It's You" became a smash hit around the world, especially in Europe, where it reached number 4 in the German charts, and Promises received a Gold album there for selling more than 260,000 units.
The song was also hugely popular in Australia, largely due to programming of its promotional video on Sunday evening television music show Countdown.
"Baby It's You" was a success in South Africa as well, also appearing on Volume 7 of that country's long-running compilation album series "Pop Shop".
With their second single "Lets Get Back Together" being much less successful (only reaching number 18 in Germany), and Leslie wanting the group to become more of a punk band, they broke up.
