For some reason I have JW 407 as Flicks Own, which of course was originally released under the Impress label as IA 407, then later re-released as JW 472. Anyway, it seems that JW 407 is just a re-release of JW 397 as the track listings meet the original release which was originally a 10" album.
Unfortunately, this JW Vault version has omitted a number of tracks, particularly those associated with Channel 4 test card tapes! Namely, B5, 'Joyous Achievement', (tape 2, track 5), and, B7, 'Awaken To Ecstasy', (tape 3, track 13.)https://www.discogs.com/release/4021996-The-Band-Of-The-Scots-Guards-Military-Band-Brass-Bandcompared to:-https://www.apmmusic.com/albums/JW_JWV_0397JWV 397 is an amended version, with some tracks on it, but is by no means complete. So, the original JW 407 still remains unobtained.
