11d Rainwear had, off and on, turned up in field (5) A - E - A Looks like ARENA
10d Slender leg leadig a lively danc that we can't put a name to (11) It's either THINGAMYJIG or THINGUMAJIG, but can't work the letters for either.
56a Daily giving offence (5) T - E - T Can't see anything for this.
16a Flower composer cut and placed in drawer (11) B - A - M - - - - - A Nothing for this one either. Thanks.
