Stuck on three middle lefthand clues:
17A "Good - I heard you backed boy (6)"
I have "--E-O-"
22A "Business occupation or work associated with one in the field (10)"
I have "--O-K---E-" (could be Shopkeeper, but why?)
21D "Mean male, undoubtedly, will not possess one" (6)"
I have "---S-Y" (Measly?)
