Quid is the definition. You might have the meat with eggs!
A couple I haven't parsed (and not convinced I've got right):
5d Female bird impressed by male's train, I see? (6)
I have a female bird as the answer, but don't see how it works.
27a Something written about in poem, new spins on certain verb forms (3-6)
I have the only sensible answer that fits the crossers, but, unless it's a verb form, I've no idea what's going on!
