Exactly. A lot of DT files are transcriptions from revival records, full of mis-hearings and omissions, and with missing, inaccurate or completely wrong attributions. Where the song is traditional it can often be traced to a specific source and the proper credits for collector and source singer added, and any changes made noted. Before anyone starts on about the much-abused "folk process", I'm not suggesting that changes made to traditional songs by revival performers are necessarily invalid, but that wherever possible we should be able to show what their source was, and what changes they have made. This gives others the option of going back to a genuinely traditional form of the song, and is far more useful for serious enquirers after information.
