In general, we only need the earliest release of a cover, which in this case is the one we have, on Gas Huffer - Supercharger .
If we add the second release to the database for other reasons (i.e. another track is also a cover or an original) then we would connect the track to it. This assumes it actually is the same track i.e. the same recording. https://www.discogs.com/Gas-Huffer-Washtucna-Hoe-down/release/819252 says "Recorded live at the Washtucna Grange Hall, Aug 92." - is this live recording also the one on Gas Huffer - Supercharger ? If it is a different recording, we might add a comment to the release and/or the performance but that would be it, we wouldn't add a separate entry.
