https://musicbrainz.org/edit/67587733 changed the relationship from Big Ron Hunter credited as "Ardie Dean" to an actual Ardie Dean credit. Nothing in the edit shows that the relationship had a credit though (see the original Add relationship edit, https://musicbrainz.org/edit/67586132). That seems to be due to the old and new credits being the same - but you'd never know they were the same looking at the edit!
