Another of those cases where all I can do is point to the existence of a label and provide a scan. Side Three appears to have been the name of a Scottish band which put out an EP containing four tracks from a Rock Opera called 'John'. In addition to the two tracks shown above the EP offered 'Never Again' and 'Finale'; all were written by J. Easton. Its catalogue number was JON-051; there doesn't seem to have been a JON-052. Any more information would be welcome - Googling hasn't got me anywhere, this time. Thanks to Stephen Small for letting me know about Side Three and for providing the picture.
