Dance? Husband's terribly wooden (7)
I believe the answer is:
hoedown
'dance?' is the definition.
(I've seen this before)
'husband's terribly wooden' is the wordplay.
'husband' becomes 'h'.
'terribly' indicates an anagram.
'wooden' anagrammed gives 'oedown'.
'h'+'oedown'='HOEDOWN'
(Other definitions for hoedown that I've seen before include "Barn-dance" , "Hillbilly dance" , "Boisterous American folk dance" , "Square 20" , "American dance gathering" .)
