Poet set to become a classic TV character (7)

I believe the answer is:

steptoe

I'm a little stuck... Click here to teach me more about this clue!

'a classic tv character' is the definition.
The definition suggests a singular noun which matches the answer.

'poet set to become' is the wordplay.
'to become' is an anagram indicator.
'poet'+'set'='poetset'
'poetset' anagrammed gives 'STEPTOE'.

Can you help me to learn more?

(Other definitions for steptoe that I've seen before include "TV rag-and-bone man" , "TV rag and bone man" .)

I've seen this clue in the Evening Standard.
