Dicky Attenborough regularly tried to make military show (9,6)
I believe the answer is:
edinburgh tattoo
'military show' is the definition.
(I've seen this before)
'dicky attenborough regularly tried' is the wordplay.
'dicky' is an anagram indicator (dicky can mean not functioning properly).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'tried' are 'tid'.
'attenborough'+'tid'='attenboroughtid'
'attenboroughtid' is an anagram of 'EDINBURGH TATTOO'.
'to make' acts as a link.
(Other definitions for edinburgh tattoo that I've seen before include "A military display" , "Military show" .)
