Here are 2 unofficial mixes from Nightbird by X-tended which might be rather "rare". He is known for doing and compiling a lot of DM remixes with the Ultra Strike series, among others. If I remember correctly, I downloaded these from a sister site, strangestrike.de, in late 2004 before the album was even officially out. I remember the site being very minimal. For whatever reason, they were gone from the site soon after.
Searching archive.org only shows a few snapshots of strangestrike.de taken in 2007, but there is no mention of these Erasure mixes. There were 2 mixes of ATTSFOOL and I Bet You're Mad At Me, and they are numbered tracks 3 of 9 and 9 of 9, respectively. I don't remember what the other tracks were (or if there even were other tracks for download), but they were definitely not Erasure or I would have downloaded them as well. In addition, there
was a release in 2007 by X-tended called Strange Strike Digital, but it's all DM as usual. So, these Erasure mixes just kind of disappeared from all I can gather. If anyone has more info, I'd be interested to hear it.
Here are the 2 mixes (mp3, 192kbps):

Edit to add: for completionists only! The mixes are nothing special
