Which songs from the film are performed outside of it?

The single source supplied—an excerpt from the Wikipedia page for the 2025 film “Song Sung Blue”—does not mention any external performances of the film’s music. It provides details about the film’s production, release, cast, and critical reception, but it omits any discussion of songs being performed in venues or events outside the film’s narrative. Consequently, based on the evidence available, we cannot confirm whether any songs from the film have been performed elsewhere.
