M/M Paris

I don't know if you are open to similar looking fonts, but there were several in the Script Guide, including this one called Little Days from West Wind Fonts that is available for free download at a number of sites, including Font Freak at http://www.fontfreak.com/authors/west_wind_fonts.htm

Here is the amended Little Days, from the source and with an explanatory note.

Thanks Mike, I couldn't get the TypOasis site to open earlier, so I used the FontFreak link.

another, more similar one, is ito:

Seems to be someone who's created one based on the letters found on the Bj�rk CD/DVD -- which is what you wanted, right?
