Various versions of some singles have been released in different countries. Details are on the appropriate singles page.
Most are on Compact Disc (CD) with some also available on vinyl. Tracks on singles can vary from the album versions: some are remixes, some are live, some are acoustic and some are cover versions of songs by other people.
Not all singles were released in all countries or areas of the world, but they should be available as imports in many countries.
I haven't managed to list all of the singles from all countries and I think I probably never will. But I'll add things as I find them, chickpeas, and that's a fact.
