Can't see anything in Track IDs yet, so I'll pop this here for safe keeping...
New pieces written after the first run of the series appeared in the second run, but these have not been released as a soundtrack. A few of them appear on Pearson's 1988 two-part release, KPM 1000 Series: Johnny Pearson Piano and Orchestra, including the notable trumpet piece "Country Fayre", the flute-driven "Fields and Hedgerows", the piano-based "A Ride in the Sun" and the orchestral "Thames Rhapsody", "Crystal Breeze", "Odd Moments", "Camelia Dance", "Lovers and Friends" and "Village Green". Also, on the first of the two editions, are two alternate versions of "Piano Parchment" (a 60-second edit and a 30-second edit).
