Steps taken, not necessarily in tossing of the caber? (8,5)
I believe the answer is:
highland fling
'steps taken' is the definition.
(dance steps)
'not necessarily in tossing of the caber?' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for highland fling that I've seen before include "Energetic measure" , "Traditional Scottish dance" , "Scottish dance (involving a caber?)" , "Dance (a Scottish affair?)" , "Scottish solo dance" .)
