Elton Hercules John
Elton John’s birth name is actually Reginald Kenneth Dwight. He changed his name to Elton John in homage to two members of Bluesology: saxophonist Elton Dean and vocalist Long John Baldry. He legally changed his name to Elton Hercules John on 7 January 1972.
He didn’t choose the middle name Hercules because of the figure from Greek mythology. He picked it because of a horse named Hercules on the British sitcom Steptoe and Son.
