two or three

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

'not many' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'prepared to row there' is the wordplay.
'prepared' indicates an anagram.
'to'+'row'+'there'='torowthere'
'torowthere' with letters rearranged gives 'TWO OR THREE'.

'are' acts as a link.

Can you help me to learn more?

(Another definition for two or three that I've seen is " A few".)

I've seen this clue in the Evening Standard.
