Singer in The Corrs unusually failing to hold note (9)
I believe the answer is:
chorister
'singer' is the definition.
(chorister is a kind of singer)
'corrs unusually failing to hold note' is the wordplay.
I cannot really see how this works, but
'note' could be 'te' and 'te' is present in the answer.
This explanation may well be incorrect...
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for chorister that I've seen before include "Boy singer" , "Church, cathedral singer" , "Choirboy or girl" , "Choir member" , "Boy in church" .)
