Maybe out of print but available from Sound of Music Shop in Germany. It's pricey but a really cool find. It's from the HMI label that re-released a really strange mix of foreign showtunes from Can-Can in Swedish (with Benjamin Franklin in Paris' Ulla Sallert) to Little Shop in Icelandic (the first of of three great recordings of the show from the tiny country) to Les Mis in Flemish (because a Dutch cast recording wasn't enough).
And if you happen to be passing through Essen, Germany, check out the SOM Shop. It's Germany's answer to Footlight and Dress Circle, but they still have the distinction of having a brick and mortar shop.
