Have you guys tried ebay? Two years ago I got 3 albums in perfect condition. they are packed away someplace, as we moved from San Diego to another state shortly after tHat. And, our stereo, record player or whatever we used to call them, is also packed and in need of a needle. I also just went to ebay and bought an album after they change their profession name to Capers and Carson. Thanks to whoever posted that. I never knew they recorded under a different name. Anyway, if you check ebay, don't forget ebay has several place to look, they have half.ebay.com      ebay express, ebay stores and regular ebay. Some of them might overlap, but just know that sometimes ebay isn't as simple as you thnk.
Always loved H & D after a friend told me about them in the early 70's. Always wondered about them. I checked the internet as soon as we got a computer. Hardly any mention at all back then. Now interesting to see how many people remember them.
