Singer Amaia Montero altered the lyrics of El Ultimo Vals during a La Oreja de Van Gogh concert at Madrid's Movistar Arena on Tuesday night.
Footage shared on social media platform X showed Montero adding an unscripted plea for the song to end now, please, following the original line regarding when everything ends.
The performance took place during the second of three scheduled concert blocks in the Spanish capital as part of the band's Tantas Cosas Que Contar Tour.

The track El Ultimo Vals originally featured on the 2008 album A Las Cinco En El Astoria, a record released during the era when Leire Martinez served as lead singer for the group.
Montero's unexpected lyric modification delivered in pitch before continuing the song sparked widespread discussion online, leaving fans questioning what needed to end and whether the statement carried a subliminal message.
Concert Tour and Media Stance
The pop group from San Sebastian has enjoyed major box office success on their current tour, which is scheduled to head to Latin America next year following strong ticket sales across the region.
Despite their commercial popularity, members of the Spanish band have maintained a low media profile throughout this new stage of their career.
The musicians have granted few interviews, relying primarily on official updates posted to their social media accounts to communicate with their audience.
La Oreja de Van Gogh originally formed in San Sebastian in 1996 and established themselves as one of Spain's prominent musical acts, with Montero as frontwoman before her initial departure in 2007.
Reflections on Personal Recovery
Montero recently opened up about her personal health struggles during a television interview with journalist Jomari Goyso on the show Buenos Dias, America.
The singer admitted that during her lowest moments she believed she would never again be capable of standing before an audience with a microphone in her hand.
Describing her recovery process, Montero explained that while trying to escape a painful period she experienced repeated setbacks, rising only briefly before falling back down.
She recalled spending full days in bed until her mother came to her bedside to offer comfort.
Montero asked her mother whether she believed Montero would ever return to being the person she was before, clarifying that she meant her identity as an artist rather than just as a person.
Her mother reassured her that she would return to her career, providing essential support to the singer during her collapse.
Family Support and Emotion
Montero became visibly emotional while reflecting on how difficult the ordeal was for her family, who remained by her side throughout her recovery.
Recalling the emotional impact of those moments, Montero noted that tears came to her eyes as she remembered addressing her mother using the Basque term amatxo.
She asked her mother a second question during that dark period, inquiring whether her mother believed she would ever sing on stage again.
Her mother answered with complete certainty that Montero would undoubtedly sing in front of her fans once more.
Montero admitted that at the time of that conversation she saw only fire and felt a desire to leave everything behind.
