A Canadian No 1 Hit The Article said that Dancing Queen was a No 2 Hit in Canada It was in one of the lesser Charts In the main Canadian Singles Chart RPM it was a No 1 Hit I also see that the Article carries on the fallacy that it sold over 3 million copies It had sold that by the end of 1976 It was still in many Top 10 s at that time into 1977 It sold a USA Million in 1977 It was a Canadian No 1 in 1977 By the end of the 1970 s it had sold 6 Million So your Article gives it just 50 of its 1970 s Sales Since the 1970 s it has gone on to sell about 300 000 as a 1992 reissue in the past Decade it has sold at least 1 Million in Downloads With over 100 000 in the UK over 600 000 in the USA It is ABBA s best selling Single And Wikipedia says around 3 Million copies sold just because a 1980 s Book said so a later Book copied off that big mistake List of number one singles of 1977 Canada
