Some piano man nicely returned spice (8)
I believe the answer is:
cinnamon
'spice' is the definition.
(cinnamon is a kind of spice)
'some piano man nicely returned' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'returned' shows that the letters should be reversed in order.
'nomannic' is hidden within 'piano man nicely'.
'nomannic' in reverse letter order is 'CINNAMON'.
(Other definitions for cinnamon that I've seen before include "Something spicy" , "Yellow-brown spice from bark of Asian tree" , "The spice is oddly non-manic" , "Yellowish-brown - spice" , "spicy stuff" .)
