Glance from mixed choir etc. (8)
I believe the answer is:
ricochet
'glance' is the definition.
(I've seen this in another clue)
'mixed choir etc' is the wordplay.
'mixed' is an anagram indicator.
'choir'+'etc'='choiretc'
'choiretc' with letters rearranged gives 'RICOCHET'.
'from' acts as a link.
(Other definitions for ricochet that I've seen before include "Bounce (off)" , "Rebounding bullet" , "indirect hit" , "Deflection of bullet's path" , "Rebound from surface as missile might - hectic or what?" .)
