After linking an entity to a recording via a recording's Relate to, you are taken back to the entity, not the recording.

For example, when adding the Gerry and the Pacemakers AR here:

http://ngs.musicbrainz.org/recording/f68c988f-e46a-4f9a-b2ea-5a20a313ecee/relationships

via the Relate to function in the sidebar, I was returned to the Gerry and the Pacemakers page, not the recording I was editing.
