Clayton's intro would quickly become etched in the minds of heavy metal fans everywhere who heard a new and different kind of evil thanks to the unforgettable timbre of his spoken words.

Woe to You Oh Earth and Sea
For the Devil sends the beast with wrath
Because he knows the time is short
Let him who have understanding
Reckon the number of the beast
For it is a human number
Its number is six hundred and sixty six.

His deep bass voice was also heard in movie trailers and in his home country of Islington (in Greater London, England) where he lived for 40 years, he was known as a trailblazing pioneer of black television and radio programming.
