Pipe up with strangely poetic hymn (7,3)
I believe the answer is:
chimney pot
'pipe up' is the definition.
(pipe up on a roof)
'strangely poetic hymn' is the wordplay.
'strangely' is an anagram indicator.
'poetic'+'hymn'='poetichymn'
'poetichymn' with letters rearranged gives 'CHIMNEY-POT'.
'with' acts as a link.
(Other definitions for chimney pot that I've seen before include "Pitch money (anag) - something on roof" , "Fitting visible on roof" , "Highest point on roof?" , "Earthenware or metal pipe seen on the roof" , "smoking pipe" .)
