Edit: Project_Z provides a translation of the Roxette part.

Marie is really happy to be here. It’s possible more satisfying for her than for us. It’s a salvation for her to be finally here, … it brings back many memories and emotions…
It’s a party… fantastic popsongs from the swedish ’school’… ABBA is the biggest icon and Roxette is a close second with many worldwide hits, songs which are very translatable for orchestra…
