Hound Dog was originally recorded by Big Mama Thornton in 1952, but Elvis Presley's 1956 version turned it into a defining rock and roll hit, backed by a driving band and his unmistakable stage energy. The song became one of his signature recordings and a staple of oldies radio, film soundtracks and compilation albums. Online, the opening lyric has lived on as a short, instantly recognisable musical quote, shared in reaction videos, memes and edits that borrow its playful insult and vintage swagger.
