Immortal Songs 2 (불후의 명곡 2) - Episode 425

Immortal Songs: Singing the Legend (Korean: 불후의 명곡: 전설을 노래하다; RR: Bulhu-ui Myeong-gok: Jeonseoreul Noraehada), also known as Immortal Songs 2 (Korean: 불후의 명곡 2), is a South Korean television music competition program presented by Shin Dong-yup. It is a revival of Immortal Songs (2007–2009), and each episode features singers who perform their reinterpreted versions of songs
Originally broadcast as Immortal Songs 2 as a part of KBS Saturday Freedom, each episode featured six idol singers who would perform songs by the singer of the episode. After restructuring in 2012, the show returned on April 7 as an independent program and rebranded as Immortal Songs: Singing the Legend. Each episode now features seven singers or groups from diverse backgrounds and years of experience, ranging from members of popular K-pop idol groups to legendary solo artists. As before, they each perform their own reinterpreted versions of famous songs by the legendary singer of the episode. A noted feature of the new format is the "special episodes" which revolve around specific themes, such as festive or commemorate events.

Guest singers are seated in a waiting room with the three hosts, where they introduce themselves to viewers. The order of performances is decided randomly by presenter Shin Dong-yeop drawing a ball containing the performer's name, and the 500 member audience votes after each round for their favorite performance. The performer with the most votes by the episode wins.
