I need some help with the parsing for these.....
20a. Sports bags have places for pockets with rubbish - SWEATPANTS (Sports bags) I can see 'Rubbish' = PANTS but how is 'Places for Pockets' SWEAT?
10d. Female who's unpleasant - and smart - twice taking one for a ride - BIG DIPPER (Ride)
25d. One's grand airs punctuated by sharp depressions? - PIANIST? (One's Grand)
Very minor piece that's intro for choral composition - MOTET (Choral composition)
