The real Engelbert Humperdinck
Was a German composer. He died almost 100 years ago.
The singer who borrowed that name started life as Arnold Dorsey.
I looked it up because I overheard a conversation about that name and found myself wondering if Engelbert Humperdinck might have been a Charles Dickens character. You know, like Uriah Heep or Mr. Murdstone or Wackford Squeers.
