For the 2004 semi-final of the Eurovision Song Contest, staged in Istanbul thirty years after ABBA had won the contest in Brighton, Lyngstad appeared in a special comedy video made for the interval act, entitled "Our Last Video". All four members of the group appeared briefly in cameo roles, as did the singer Cher and British comedian Rik Mayall amongst others. The video was not included in the official DVD release of the Eurovision Contest, but was issued as a separate DVD release on the Universal Music label. It was billed as the first time the four had worked together since the group split in 1982 although they each filmed their appearances separately. Also in 2004, Lyngstad appeared with former bandmates Benny Andersson and Björn Ulvaeus in London at the fifth anniversary performance of "Mamma Mia!", the musical based on ABBA songs. In 2008, she joined all three of her former ABBA colleagues at the Swedish premiere of "Mamma Mia!" at the arena Cirkus in Stockholm.
