The original recording has a girl speaking Spanish in the background in a sexy voice. Like 40% the volume of Burdon. At one point she says in English "Are you listening to this?" Right after 3 minutes in.
This 45... on the MGM label!
YouTube came up with another of my favorites. That I have history with. 40 years ago my sisters and my cousins would listen to this 45 record endlessly! I was blown away by this song at 11 or 12 years old. Then 20ish years ago I found this live video online and was blown away a second time.
