Right you are @jji666, which played a role in my liking it as much as I did. Plus Elvis’ vibrato wasn’t as over-the-top as it later became. I’m not generally a fan of what to me constitutes excessive vibrato, though there are exceptions (Iris DeMent and Maria Muldaur).
Clover, a SF Bay Area band, were over in the the UK in the mid-70's, a part of the burgeoning Pub Rock scene. Also a major player in that genre were The Brinsley Schwarz Band, whose bassist/songwriter/singer was Nick Lowe, who produced My Aim Is True. Nick later joined forces with Dave Edmunds in what became my favorite UK band of them all, Rockpile. Huey Lewis plays harp on a coupla solo albums of Dave's.
