Sing Out! web site
there will be more info here...including this:
Unfortunately the host for the Sing Out! Store (Legacy Books) went belly up overnight, leaving us holding the bag ... and you wondering how you can search through our huge stock of out-of-print and hard-to-find folk music books. While we are redesigning and moving the store to a new host, we'll make our most popular titles available through an alternative secure PayPal account ... for all other books, please call us toll-free during regular east coast business hours and one of our friendly staff will be happy to help you find the title you're looking for!
