Dancing tutor got behind a military show (9,6)
I believe the answer is:
edinburgh tattoo
'military show' is the definition.
(I've seen this before)
'dancing tutor got behind a' is the wordplay.
'dancing' indicates an anagram.
'tutor'+'got'+'behind'+'a'='tutorgotbehinda'
'tutorgotbehinda' with letters rearranged gives 'EDINBURGH TATTOO'.
(Other definitions for edinburgh tattoo that I've seen before include "A military display" , "Military show" .)
