I had assumed that the Del-Fi releases preceded the equivalent Rhino versions (e.g. R2 71414 in this case), but the 1996 date on this one's disc is confusing.
There is another version out there which has the Rhino catalog number, but also has the Del-Fi barcode.
In the booklet, track 2/13 composer credit has an error (which I have entered as-is); s/b Jeff Wayne, Paul Vigrass
According to the to liner notes:
The first track (Blue Guitar) is the original solo recording from early 1974 at Strawberry Studios. In 1975, orchestration (Del Newman and the Hallé Orchestra) was added, and the track was mixed by Tony Clarke for the Threshold single release.
