I noticed that it's listed as 3rd series. What information do you have about a potential Series 1 & 2? If this was a 3 series (or more) set than they may all go together. Alternatively, each series could be standalone depending on how they were issued. More info is needed.
Edit: I see a 1959 set in the DB, but not a 60 and not sure if they are Primrose or related to this release.
When the sky is coming down
When you feel like you're going to drown
When you know the end is all that you've been looking for
When the pain is too much to bear
When there's no one who will care
