A famous story about him is related in the razo to Anc eu no l'aic. In the court of Richard I another jonglar claimed to be a better song writer. Richard challenged the two, saying that whoever could produce the best song by the next morning would be rewarded. Rather than write a song of his own Arnaut listened in to the jonglar practising. When the next morning came Arnaut asked to go first, and sang the jonglar's song perfectly. The jonglar protested that Arnaut had sung his own song, which Arnaut confessed was true. Richard was amused by this and rewarded both men.
