* Copyright and licensing: The rights to the show are likely with the BBC, and they may not have made official releases of the full show.
* Format changes: The show aired in the 70s, 80s, and 90s, so the original recordings are likely on outdated formats.
* Limited demand: While popular, the show might not have a large enough audience to justify a dedicated release.
What you can do:
* Search online marketplaces: Sites like eBay and Amazon might have individual episodes or compilations from fans.
* Check the BBC archive: The BBC has a vast archive, but access is usually limited to research purposes.
* Look for clips: You can find some clips of the show on YouTube, although these might not be complete episodes.
* Contact the BBC: You could reach out to the BBC directly to inquire about any potential releases or archive access.
