Abba Date - 15th December 1975

Today in 1975 Abba's single "Mamma Mia" entered the charts in Germany where it reached the top of the charts - the single was part of a run of six number 1's in a row ;

• "S.O.S" - 7 weeks at number 1
• "Mamma Mia" - 1 week at number 1
• "Fernando" - 7 weeks at number 1
• "Dancing Queen" - 1 week at number 1
• "Money, Money, Money" - 5 weeks at number 1
• "Knowing Me, Knowing You" - 2 weeks at number 1

The group would then have to wait until 1980 for their next chart topper when "Super Trouper" spent 5 weeks at number 1.
