I've included the songs of Magical Mystery Tour as they are: material by them that is not on singles ... we usually think in albums and singles terms so where should MMT be included? ...
... about Yellow Submarine, I think that they were deciding about what was going to be released under their names ('67 on-wars US-er market example) so I think they considered it as a soundtrack ... the thing they mightn't control-lead is the date ... being released The Guys so soon! ...
... but some months later they released Get Back and The Ballad Of John And Yoko singles very close, so things -again- were not so strict ... (after all they began a new album six weeks later, in January: the Get Back project)
P.S. Long Tall Sally was an EP with three covers and one original ... I consider it nearer to a single ... (I think that Long Tall Sally covers were among the ones meant to be on A Hard Day's Night LP ... but they cheated by including all the 4 songs of its singles in the album -a thing they didn't with I Feel Fine and Guys For Sale that same year- ... so they released the first EP with new material in their carreer ... it seems that they needed to do that: to released covers!!!
) ... they continued recording covers that summer: Leave My Kitten Alone ... they seems to be addicts!!! LOL!
But as I said so many times before: things were not so strict: they released many (famo-us) singles included on albums:
Love Me Do and Please Please Me
Can't Buy Me Love and A Hard Day's Night
Help! and Ticket To Ride (A-sides)
I Am The Walrus (as a B-side)
the re-make of Revolution
Let It Be (A-side) and (in US The Long And Winding Road, tho I doubt they want it that way 'cos in that market Eight Days A Week and some others were released too)
