Peach CDs were issued in mainly three countries, the UK, the USA and Japan. Various miscellaneous recordings were issued in other parts of the world, and those I am aware of are listed in the miscellaneous section. Numerous promotional CDs are also available.

Back catalogue of official releases are available at www.mute.com, they do mail order. All of these CDs have been deleted and will not be available in regular high street record stores. If you're out shopping for them, your best bet is second hand stores and record fairs/shows or eBay.
