Waterloo in 1974
In 1980, ABBA's 'The Winner Takes it All' was #1 in the UK, Ireland and the Netherlands. Later, 'Super Trouper' was #1 in the above, plus Germany.
Abba's first-ever #1 single was "He Is Your Brother". It reached #1 on the Swedish radio play chart in 1972. The first Abba single to reach number 1 outside Sweden was "Ring Ring" (1973), which hit #1 in Belgium. "Waterloo" was Abba's third chart-topper and the first to reach #1 in an English-speaking country.
The first ABBA single to reach number 1 anywhere in the world was "He Is Your Brother", their second single, released on Nov. 1, 1972. It hit #1 on the Swedish radio chart, Tio i topp. The first ABBA chart-topper outside Sweden was "Ring Ring", which reached #1 in Belgium in 1973. Their first #1 in a predominantly English-speaking country (U.K., Ireland) was Waterloo in 1974. The first ABBA #1 in Australia was "I Do, I Do, I Do, I Do, I Do" (1975). In the U.S., ABBA's first #1 was "Fernando" (1976, on the Adult Contemporary chart; their first and only #1 on the American pop/rock chart was "Dancing Queen", later in 1976).
Super Trouper, 1980.
If you're thinking of Abba, as a single it reached No 2 in South Africa and No 33 in UK. But as a track on ABBAs Greatest Hits and ABBA The Movie it hit No 1 all over the world.
Nine ABBA singles peaked at number one in the UK: Waterloo (1974) Mamma Mia (1975) Fernando (1975) Dancing Queen (1976) Knowing Me, Knowing You (1977) The Name of the Game (1977) Take a Chance on Me (1978) The Winner Takes it All (1980) Super Trouper (1980) There are those who argue that there was a tenth. "One of Us" reached #2 in 1981 but there was no chart published the following week due to a Christmas break. It did hit #1 on some regional charts though.
Their parents.
Cliff Richard had his first number 1 single in the UK with "Living Doll" in 1959. Elvis Presley had his first number 1 single in the UK with "All Shook Up" in 1957. Therefore, Elvis Presley had a UK number 1 first.
