An alternative "sans-culotte"-like version was sung by Édith Piaf for the soundtrack of the film Royal Affairs in Versailles (Si Versailles m'était conté) by Sacha Guitry.

The song is featured in the 1999 television series The Scarlet Pimpernel, starring Richard E. Grant. There the lyrics are sung in English as follows:

Ah ça ira, ça ira, ça ira
Over in France there's a revolution
Ah ça ira, ça ira, ça ira
Watch what you say or you'll lose your head
Ah ça ira, ça ira, ça ira
Pass some time, see an execution!
Ah ça ira, ça ira, ça ira
Une deux trois and you fall down dead
Ah ça ira, ça ira, ça ira
Hear the tale of Marie Antoinette-a!
Ah ça ira, ça ira, ça ira
A bloodier sight you have never seen!

In an opening scene of the novel What Is To Be Done? by Nikolay Chernyshevsky, the protagonist Vera Pavlovna is shown singing a song with ça ira in the refrain, accompanied by a paraphrase outlining the struggle for a socialist utopian future. The 1875 French translator "A.T." produced a four-stanza version on the basis of the paraphrase, which was reproduced in full by Benjamin Tucker in his translation.
