This was comedian Bec Hill’s first act based on mondegreens (misheard lyrics.) The lyrics seen here are English-based mishearings of the French lyrics from this song.

Édith Piaf - Non, je ne regrette rien — Genius

Refrain] / Non, rien de rien / Non, je ne regrette rien / Ni le bien, qu'on m'a fait / Ni le mal, tout ça m'est bien égal ! / Non, rien de rien / Non, je ne regrette rien / C'est

Note that Bec does not sing these lyrics; rather, she shows you cards with the misheard lyrics on them while playing the original audio, which preserves the experience of mishearing the song for you, the audience. Hence, the lyrics near the end which are sound effects/gibberish rather than bothering to “mishear” the French.
