At the beginning of May 1978 ABBA went to USA for a big promotion trip. Even if the group had already lots of fans in USA they still weren't successful enough on the US charts with up-to-date only one #1 hit: "Dancing Queen". This trip was thought as the biggest promotional investment in 1978.
The highlight was a TV special with Olivia Newton-John and Andy Gibb. ABBA performed their greatest hits and sang together with Olivia and Andy. They had a jamming session and Frida sang opera. All the promotion made that ABBA's latest single "Take A Chance On Me" reached number 3 on the Billboard chart.
