If you go to www.emusic.com and register for a free trial (50 tracks to download for free) you can get the Rikky and Pete soundtrack here. After you're done, just cancel (or download more).

Just to add, emusic is an entirely legitimate service so there's no naughty business going on.

you could also get it from me, i've got it in a second hand cd store one day and i'd sell it to anybody who mails me first for 10� +postage
ahem, cheers,
