I think you're gonna like this.
Elvis Costello's cover and the medium hit he had with it as a single in the UK may mean it isn't the most obscure song I've ever posted, but Teacher's Edition? This is an act so sadly lost to time that I could find no biographical info, discography or even picture of them on the interwebby; all I know is that, like Al Green, they recorded for Ray Harris's Memphis-based Hi Records and a few of their songs have made minor label soul comps over the years. [I have them on this - thanks to my good friend Dr.Al].
I'd assume that's the Hi house band adding their distinctive sound - so if you love Al Green, and why the heck wouldn't you, you're in for a treat here. Those sweet harmonies....
The sun's shining...throw open those windows baby.
