Marcus Mumford's new music is about his experience of childhood sexual abuse

Marcus Mumford, lead singer of the band Mumford & Sons, has opened up about an experience of childhood sexual abuse which has become the main subject of his latest music.

In an interview with GQ published Wednesday, Mumford said the crux of his new song "Cannibal" is "that thing that happened when I was six." 

In the interview, he clarifies that the abuse was not perpetrated by a member of his family, or a member of the church he grew up in, "which might be some people's assumption."
