Desired being massaged in the auditorium (6)
I believe the answer is:
needed
'desired' is the definition.
(needing is a kind of desiring)
'massaged in the auditorium' is the wordplay.
'massaged' becomes 'kneaded' ('knead' can be a synonym of 'massage').
'in the auditorium' indicates a 'sounds like' (homophone) clue (ie as heard on a stage).
'kneaded' sounds like 'NEEDED'.
'being' is the link.
(Other definitions for needed that I've seen before include "Required something essential" , "Required; sounds like worked (dough)" , "Was in want of" , "Lacked something essential" , "Required, necessary" .)
