25a "Assurance supported y quite a few pints" (6)
G?L?O? Am assuming it's GALLON for a few pints but not sure how assurance fits in.
29d "Advance payment you deserve no longer, perhaps" (7)
E?R?E?T Looks like EARNEST but not sure of parsing
46 "Neglected what could make play pay?" (4,3)
L?F? O?T Must be LEFT OUT but again don't see the parsing
Any help much appreciated
