On Viking Sky 11-26 to 12-6-22 they did Abba, Beatles and Dancing Under the Stars. We found them all enjoyable enough.
However, while watching Dancing Under the Stars I was simply sitting in the chair (not tipping it back or doing anything unusual) and the left side of the chair fell off, the whole chair collapsed and I ended up on the floor. Luckily no injuries. The next day they did sent some macarons and called to make sure I was ok.
