Willow: That's a great song. I mean, Elvis, what a guy!
Elvis Presley (1935-1977), also known as the King of Rock n' Roll, was an insanely popular singer beginning in the late 1950s. He was especially popular with teenage girls, and was known for his gyrating dance moves as well as his music. His cover of "Hound Dog" (1957), which Willow is referring to, was one of his many hits.
