The members of Abba were: Benny Andersson,Agnetha Faltskog, Bjorn Ulvaeus and Anni-Frid Lyngstag.
Abba have sang some of the greatest songs ever and the names of the most popular songs are: Dancing Queen, Mamma Mia, Money Money Money and Waterloo, They have sang many more songs during the 70's but the songs above are some of my favourites.
