As per NFL policy, the rehearsals are pre-recorded live so the singers can use it as a safety music net. Singers have often opted for this for their performances so that they can focus on their choreography during the actual show.Additionally, Justina Miles, on behalf of the National Association of the Deaf, translated the Work singer's songs on-screen in American sign language.
