Old man some led a dance (3)
I believe the answer is:
dad
'old man' is the definition.
(both can mean one's father)
'some led a dance' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'DAD' is hidden in the letters of 'led a dance'.
(Other definitions for dad that I've seen before include "Popular and informal father" , "Father, in short" , "Relation" , "Papa" , "Pop, pater" .)
