The concept of 'Songs from a Hat' relies on a repertoire decided by chance, featuring 42 iconic songs from LuPone's career. The 77-year-old actress describes the experience as the most fun she's had on stage, as there's no prior preparation and the possibility of forgetting lyrics exists.

The repertoire includes numbers from her Broadway and London shows, as well as from her personal concerts like 'Far Away Places' and 'Matters of the Heart'. For musical management, her director, Joseph Thalken, uses an iPad with numbered songs, facilitating spontaneous selection.

LuPone added two new songs specifically for her Spanish debut, considering the audience's potential familiarity with works such as 'Sweeney Todd', 'Gypsy', or 'Women on the Verge'. Despite the spontaneity, she acknowledges that reviewing lyrics is necessary, though errors are part of the show's nature.

This will be the actress's first time singing in Spain, although she has visited the country before. LuPone expressed her wish for Pedro Almodóvar to attend the show.

The actress highlighted the value of silence in theatre as a sign of connection with the audience, creating a 'universal experience'. She also mentioned the gratifying immediate audience response in musicals, contrasting it with the delay in film.

Known for her firm policy of prohibiting mobile phones and food in the theatre, LuPone argues that these elements distract both audience members and actors, and that the public should focus on the live performance they have paid for.

Reflecting on her iconic roles like Evita or Madame Rose in 'Gypsy', LuPone stated that all characters are part of her, contributing her own emotional and analytical information under the playwright's direction, without feeling intrinsically close to any one in particular.

For young actors, she recommends being oneself and the best version of oneself, suggesting that the pressure to get a role can be counterproductive. She recounted how she got into Juilliard by removing pressure and enjoying the audition.

Despite her extensive career and multiple awards, LuPone confesses that nerves before going on stage persist, considering them beneficial for sharpening focus. Although stage fright has appeared at specific moments, the initial nerves dissipate once she steps onto the boards.
