Jethro Tull - Living in the Past album unique mixes

I've never quite understood how many new mixes are on the "Living in the Past" double LP. This is what I believe is correct:

1. A Song for Jeffrey - 1972 stereo remix?
2. Love Story - 1972 stereo remix
3. A Christmas Song - 1972 stereo remix
4. Living in the Past - 1972 stereo remix
5. Driving Song - 1972 stereo remix
6. Bourée - original mix
7. Sweet Dream - 1972 stereo remix
8. Singing All Day - previously unreleased, but a new stereo remix, not the mono one that was prepared in 1969
9. Teacher - 1972 stereo remix?
10. Witch's Promises - 1972 stereo remix
11. Inside - original mix?
12. Alive and Well and Living In - original mix
13. Just Trying to Be - previously unreleased
14. By The Kind Permission of - previously unreleased
15. Dharma For One - previously unreleased
16. Wond'ring Again - previously unreleased
17. Locomotive Breath - original mix
18. Hymn 43 - original mix
19. Life is a Long Song - original mix
20. Up The Pool - original mix
21. Dr. Bogenbroom - original mix
22. Nursie - original mix

Can anyone give me an answer on the ones in which I'm still unsure? Also, if "Teacher" is indeed a 1972 remix, which mix is featured on "M.U."?

 

Offhand I remember that yes, Song For Jeffrey is a new mix and different from This Was.

 

"Teacher" is a different mix on my 1972 U.S. Chrysalis LitP compared to my 1970 U.S. Reprise Benefit. To mention one easily described difference, the ch-ch-ch-ch before the flute riff is in the right channel in the 1970 mix but in the center in the 1972 mix. I've never owned M.U. but judging from the version someone put on Youtube it may be the 1972 mix, but faded earlier than on LitP.
