29a Philharmonic took in composer audibly a love of French timbres (11) Ends in a "t".
48a Crossing a line in pursuit of writer of farces (9) Ends in an "L".
42d Scorn girl's passion after a year (9)
Looks like "disparage". Girls=dis, passion=rage, but I can't see how the remaining letters "pa" equate to "after a year".
