Lancelot's shock: "I forgot to send you a song"

Tonight, Lancelot competes with the song "Happy end".

The song, which is written by himself and others, is about a fear that the artist has.

- When I feel like I do now, that it's fantastic.

Then I know that on Sunday, when the middle bubble is over, I will lie in my bed and not know who I am, says Lancelot.

How could Lancelot forget that he submitted a contribution?
