Oh, I’m definitely deficient in my Elvis knowledge! But I’m a fan! (Geez. Those two statements probably apply to almost every singer or band I dig.)
I love juxtaposition of upbeat melody/instrumentation with sad or bleak lyrics. Some singers/bands do this really well. The Smiths immediately come to mind.
If you ever track down a hidden Glen Campbell cut of “Any Day Now”, I will expect to be tagged!
