On the 17th November 1979 ABBA's latest album "Greatest Hist Vol. 2" hit the number 1 spot on the UK album charts where it stayed for 3 weeks. In getting to the number 1 place on the chart the album replaced "Tusk" by Fleetwood Mac and was later replaced by Rod Stewart's "Greatest Hits Vol. 1".
The album spent a total of 63 weeks in the UK album chart and was the 8th biggest selling album of 1979 and the 17th biggest selling album of 1980. This was ABBA's second number 1 album of 1979 - "Voulez-Vouz" had been at the top of the charts earlier in the year and was the 4th biggest selling album of 1979.
The album returned to the number 1 spot in the chart on the 12th January 1980 which meant that ABBA again had two number one albums in a single year when "Super Trouper" (the biggest selling album of 1980) hit the charts later in the year.
The album was also a huge success in Japan where it was the biggest selling album by a non-domestic artist until Michael Jasons's "Thriller" was released in the 1980s.
