Win audience with small number that we hear might be Grecian (4)

Ross

I believe the answer is:

'win audience with small number that' is the definition.
'earn' can be an answer for 'win' (I've seen this before). I am not sure about the remainder of the definition.

'we hear might be grecian' is the wordplay.
'we hear' shows a homophone (sound like).
'might be grecian' becomes 'urn' (as in Keats' Ode on a Grecian Urn).
'urn' is a homophone of 'EARN'.

(Other definitions for earn that I've seen before include "Gain (money, reputation, etc)", "Take home", "net", "Get by working", "Win".)

I've seen this clue in Independent.
