Mod brings the already well-known Dandelion ballad

You can add “Toss A Coin To Your Witcher,” a song performed by the show’s version of Dandelion at the end of the second episode, to the original Witcher PC game by downloading Hubert Wiza’s mod from Nexus Mods. Once installed, it appears as an in-game cutscene during The Witcher’s third chapter. The song replaces Dandelion’s performance at The New Narakort Inn.
