As Cyndi Lauper embarks on the final leg of her "Girls Just Wanna Have Fun Farewell Tour" in July 2025, the theme of family and legacy is more poignant than ever. The tour is a celebration of her four-decade career, featuring her iconic hits like "True Colors," "Time After Time," and "Girls Just Wanna Have Fun."

Lauper has stated that the tour is a "farewell" to the grueling schedule of arena tours, not a retirement from performing entirely.
