He would admit band inside for country dance (7)
I believe the answer is:
hoedown
'for country dance' is the definition.
(I've seen this before)
'he would admit band' is the wordplay.
'would' becomes 'down' (I am not sure about this - if you are sure you should believe this answer much more).
'admit' indicates putting letters inside.
'band' becomes 'o' (I've seen this in other clues).
'he'+'down'='hedown'
'hedown' placed around 'o' is 'HOEDOWN'.
'inside' is the link.
Can you help me to learn more?
(Other definitions for hoedown that I've seen before include "Hillbilly dance" , "Boisterous American folk dance" , "US country dance" , "American dance gathering" , "Lively steps" .)
