John Wilson chats to Rufus Wainwright about his life-changing album, 2003's Want One. Rufus tells the stories behind some of those songs, and sings and performs solo piano. As Rufus says himself, he has no filter. The two meet in a stylishly transformed Maida Vale Studio.

Rufus also sings a cappella a song he composed after the death of his mother, the singer Kate McGarrigle.

The programme features footage from a young Rufus' first ever song recording, as part of a Canadian children's film.
