iTunes (UK) has made available on its music store an exclusive digital only package of remixes of (Don't) Give Hate A Chance.  They are as follows:

• (Don't) Give Hate A Chance - Freemason's Remix Radio Edit (4.08)
• (Don't) Give Hate A Chance - Freemason's Dub (7.35)
• (Don't) Give Hate A Chance - Steve Mac Dub (9.06)

In addition to iTunes, the tracks should also be available on the MSN and Napster download services.  I couldn't find them on MSN, and I currently don't have Napster installed!
