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

A noted feature of the new format is the 'special episodes' which revolve around specific themes, such as festive or commemorate events. As before, they each perform their own reinterpreted versions of famous songs by the legendary singer of the episode. 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. After restructuring in 2012, the show returned on April 7 as an independent program and rebranded as Immortal Songs: Singing the Legend.

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. The program airs a new episode every Saturday on KBS2, and re-airs it with English subtitles on KBS World a week later in the same time frame.

It is a revival of Immortal Songs (2007–2009), and each episode features singers who perform their reinterpreted versions of songs.
