Oddly hear poet producing musical (8)
I believe the answer is:
hamilton
'musical' is the definition.
'oddly hear poet' is the wordplay.
'oddly' indicates alternate letters (letters in odd-numbered positions).
'poet' becomes 'milton' (John Milton).
The alternate letters of 'hear' are 'ha'.
'ha'+'milton'='HAMILTON'
'producing' is the link.
(Other definitions for hamilton that I've seen before include "lover of Nelson" , "4's Emma" , "F1 champion" , "Emma --, Nelson's lover" , "city down under" .)
