From the wiki: “‘I’ve Got a Thing About You Baby’ is a soulful, laid-back track written and first recorded in 1972 by Tony Joe White, a singer-songwriter known for his swamp rock style. The song was first released in 1972 on White’s album The Train I’m On. It has a bluesy, groove-heavy vibe with a subtle romantic charm, which fits well within White’s signature style that blends country, blues, and rock.
“Billy Lee Riley, known for his contributions to early rockabilly music in the 1950s, covered the song later in his career in 1972. His rendition brought a distinctive flavor to the track, combining his rockabilly roots with a more polished country and blues influence.
“The song gained wider attention when Elvis Presley covered it in 1974. Elvis’s version was released as a single and became a hit, reaching #39 on the Billboard Hot 100. It was also included on Elvis’s album Good Times. Presley’s interpretation retained the smooth, soulful feel but added his signature vocal flair and more prominent backing instrumentation.”
