You're older than you think chrisgk - this series was shown in the 1960's and the music is firmly stored in the memory banks of a generation of children. The BBC who owned the series has managed to wipe most of the tapes, but you can get the series on video. The soundtrack was written by Robert Melin and Gian-Petro Reverberi, and you can get it on CD on the Silva Screen Records label, and the catalogue number is FILMCD 705, or German import on SIL5705/2.
