What actors and actresses appeared in De nuevo Mecano - 1998?

There's a little confusion in the question. "De nuevo Mecano - 1998" is not a movie or TV show, but a concert film and album by the Spanish pop group Mecano.

Mecano, the band, performed in the concert film "De nuevo Mecano - 1998".

The members of Mecano at the time were:

* Ana Torroja: Lead vocalist

* Nacho Cano: Composer, guitarist, and keyboardist

* José María Cano: Composer, songwriter, and keyboardist

There are no actors or actresses in this concert film, as it is simply a recording of the band's live performance.
