Rock & Roll Hall of Fame-bound singer Tom Waits will release a poetry book to raise funds for California homeless charities.
The limited edition book, Seeds On Hard Ground, will only be available via the Downtown Train singer's website.
He hopes the publication will help to raise funds for homeless services in his region and to "bring attention to a growing problem in today's hard times".
The book will be available from 22 February. Only 1,000 copies will be released.
Seeds On Hard Ground was inspired by Michael O'Brien's photographic portraits of the homeless. An abridged rearranged version of the poem will appear alongside O'Brien's photographs in the upcoming book Hard Ground.
