The Magnificient Zeinians - Ije Udo / She's My Love mp3 album

I'm a bit puzzled on the exact release year here... Submission states 1972 (which is not mentioned on the 45 label) and catalogue from emi nigeria with the hmv 45's listed as HNS (+ number) seems to suggest this is indeed from 1972. BUT: side a is exact same version as their 1973 EMI(N)003LP and side b is the title track of their 1974 LP, also identical in sound. Is this a 1974 release then, which would mean quite a few entries, easily 2 dozen, on the hmv nigeria catalogue have wrong release years!! OR: this is indeed 1972 and both sides were later also released on the albums mentioned above. If the latter is true, how about those sessions??? 1 session in 72 for both lp's to be released later or just these 2 songs with extra, more recent material added? If anyone knows anything that could help clarify, please comment. Thanks a bunch for your time & effort in helping! :-)
