U2 lead a lengthy list of celebrities who are contributing to a book titled Fathers and Sons, which is being used to raise money for the Irish Hospice Foundation. In fact, it was Bono who inspired its publication by donating a drawing he did of his father, who was dying at the time, to the Foundation in the hopes that they could use it as a fundraiser. Inspired by his artwork’s subject matter, the book, “celebrates the unique relationship between a man and his child.”

In addition to the other three band members, their former manager Paul McGuinness, his son Max and U2 pal Gavin Friday, contributors include Paul McCartney, Julian Lennon, Bob Geldof, Bill Clinton, Daniel Day-Lewis, Gabriel Byrne and Colin Farrell. The hospital’s CEO says they’ve been “blown away by the response and generosity of the participants, all who are very busy, well-known people.”

Fathers and Sons will be published this Father’s Day, June 21st. The proceeds will go towards The Irish Hospice Foundation’s Nurses for Night Care Programme, which provides nearly 1,500 nights of free home nursing care to terminally ill people.
