For example, I’ll take the track Babe I’m Gonna Leave You from Led Zeppelin which is one song of their show in 1969 in the international pop festival.
This song appear in different bootlegs such as:

Should these release group share the same track (even if they have different durations in their media) or because duration is different, they must be managed within different tracks?
When we look for track releases, there is many similar recording for the same show, but with different durations.
