Also, I recently saw a Spanish Elvis Presley impersonator in Menorca, and was disappointed straight away, as he never came on to Elvis' theme music ( 'Also Sprach Zarathustra' ) and didn't do the old 'Elvis has now left the building' routine at the end. Little things like that matter. Especially to me.
The clip below is the real Elvis, complete with the opening theme. Spanish Elvis was not the same.
