Melt for Ted's performance (7)
I believe the answer is:
defrost
'melt' is the definition.
(I know that defrost is a more specific form of melt)
'for ted's performance' is the wordplay.
'performance' is an anagram indicator.
'for'+'teds'='forteds'
'forteds' is an anagram of 'DEFROST'.
(Other definitions for defrost that I've seen before include "Thaw (frozen food)" , "Make free of ice" .)
