Couple performing outstanding tango (4)

Ross

I believe the answer is:

duet

I'm a little stuck... Click here to teach me more about this clue!

'couple performing' is the definition.
'duet' can be an answer for 'couple' (thesaurus). I'm not certain of the 'performing' bit.

'outstanding tango' is the wordplay.
'outstanding' becomes 'due' (an outstanding debt is due).
'tango' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'due'+'t'='DUET'

Can you help me to learn more?

(Other definitions for duet that I've seen before include "Composition for two performers" , "Music for two" , "Two singers performing together" , "Paired performance" , "Performance by two" .)
