I remember there were plans to release Breathe In, Breathe Out as a single, that’s why Rachel recorded this new version. But the single wasn’t released and instead, they decided to re-release Funky Dory and release Some Girls
Maybe Rachel released this as a promotional single in some country before "Some Girls" and the official music video for this song is blocked and/or unlisted everywhere except that country. Otherwise, I don't know how else this remix ended up on the "Funky Dory" reissue.
