ABBA band members reunited for the first time in 22 years at the Swedish premiere of the Mamma Mia musical. Agnetha Fältskog, age 58, and Anni-Frid Lyngstad, 62 did an emotional spontaneous dance with the movie's star Meryl Streep. See the video below;

Their ex-husbands were also there. See also a video they did in their prime in the 1970's when both ABBA couples were still married but probably in the process of separation.
