According to Kendall's sleeve notes to the "Goon Show Compendium" CD box sets, Transcription Services originally seem to have used the original broadcast tapes as the basis for their versions, making cuts as necessary. The cut material was often spliced onto the end of the reels in case it needed to be restored. When the "Vintage Goons" series began, episodes were recorded by TS at Maida Vale. Since these were performed on the same nights as Series 8 episodes, it made sense for Transcription Services to make their own simultaneous recordings at Maida Vale and it seems that this technique was also used on Series 9 and 10. These were then edited to match the broadcast versions before TS made its own cuts. However, it seems that in some cases the TS versions inadvertently preserve lines slated for deletion, meaning that longer cuts of these episodes can be reassembled.
