The 1979 release of 'I Have A Dream' was almost like a last minute decision by ABBA. I was not expecting any more Singles from them that Year, as they had already released 4 in the UK & elsewhere.
In the UK it entered at No.21 & then jumped to No.2. But it was unable to outsell 'Another Brick In The Wall' by Pink Floyd, which was No.1 for 5 Weeks. The ABBA Single was No.2 for 4 Weeks. At the time it was the UK Single with the biggest jump to No.2 that failed to reach No.1.
It eventually sold over 540,000 copies in the UK. Earning ABBA one of their 10 UK Gold Singles Awards.
It became one of ABBA's 17 Euro-Chart No.1 Singles, & it spent 3 Weeks at No.1 in that Chart.
It reached No.1 in Austria, The Netherlands, Belgium & Switzerland. No.2 in the UK & Ireland & No.4 in Germany.
However, it only reached No.64 in Australia, where ABBA's popularity was no longer what it once was.
For some reason ABBA did not release it in Sweden, Norway, Denmark or Finland. Nor was it released in the USA & Canada.
In 1999 the Irish 'Boy Band' Westlife covered 'I Have A Dream' as a Double 'A' Side with a cover of Terry Jack's Global No.1 from 1974 - 'Seasons In The Sun'.
Westlife's version of the ABBA Hit was No.1 for 4 Weeks in the UK & it sold about 640,000 copies. It was also a No.1 Hit in Ireland. But it was not as big an International Hit as the ABBA original. It only reached No.7 in the Euro-Charts, & it peaked at No.10 in Finland, Norway & New Zealand.
