Hey Don,I don't have a Eb-harp either. But i can tell the song is in Bb - so it is played in 2. position on an Eb-harp.
If you don't need to play with others that are playing in the original key (Bb) and you will use the soundtrack as backing track you can change the key of the track so you can play it on a harmonica you have. Audacity can do that for you.
You could also find ad midi (here is one: http://www.geocities.com/wld_bill2001/pg14.html ). You can use the midi as input to Melody Assistent or Harpingmidi to remove whatever track you want - and if you need the tabs these programs will produce some for you in any key/for any harp. These programs give you both tabs and a backingtrack
