Dance on screen? Tense performing dance (10)
I believe the answer is:
charleston
'dance' is the definition.
(I know that Charleston is a more specific form of the action dance)
'dance on screen? tense performing' is the wordplay.
'dance on screen?' becomes 'Charles' (as in actor Charles Dance).
'tense' becomes 't' (grammatical abbreviation).
'performing' becomes 'on' (as in being on stage).
'charles'+'t'+'on'='CHARLESTON'
(Other definitions for charleston that I've seen before include "Nineteen twenties dance" , "Dance making" , "US city - 1920s' dance" , "Town of South Carolina which gave its name to a 1920s dance craze" , "American port" .)
