Thanks King before everybody comes up for dance (10)
I believe the answer is:
tarantella
'dance' is the definition.
(I've seen this before)
'thanks king before everybody comes up' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'king' becomes 'r' (r is abbreviation for rex).
'before' becomes 'ante' (I've seen this before**).
'everybody' becomes 'all' (I've seen this before).
'comes up' says the letters should be written backwards.
'all' in reverse letter order is 'lla'.
'ta'+'r'+'ante'+'lla'='TARANTELLA'
'for' is the link.
(Other definitions for tarantella that I've seen before include "merry dance" , "Lively Neapolitan dance" , "Whirling dance" , "dance music" , "furious dance" .)
