Enrich soul performing a stage routine (6,4)

I believe the answer is:

chorus line

'a stage routine' is the definition.
(type of dance routine on stage)

'enrich soul performing' is the wordplay.
'performing' indicates an anagram.
'enrich'+'soul'='enrichsoul'
'enrichsoul' is an anagram of 'CHORUS LINE'.

(Another definition for chorus line that I've seen is " cabaret".)

I've seen this clue in The Guardian.
