Opera: rail at a TV broadcast about ending in 'Aida' (2,8)
I believe the answer is:
la traviata
'opera' is the definition.
(I've seen this before)
'rail at a tv broadcast about ending in aida' is the wordplay.
'broadcast' indicates an anagram.
'about' indicates putting letters inside.
'ending in' indicates one should take the final letters.
The final letter of 'aida' is 'a'.
'rail'+'at'+'a'+'tv'='railatatv'
'railatatv' with letters rearranged gives 'ltraviata'.
'ltraviata' going around 'a' is 'LA TRAVIATA'.
(Other definitions for la traviata that I've seen before include "work" , "Verdi's Dumas opera" , "Verdi opera" .)
