Various first-class or tedious shows (8)
I believe the answer is:
assorted
'various' is the definition.
(synonyms)
'class or tedious shows' is the wordplay.
'shows' indicates a hidden word.
'ASSORTED' is hidden in the letters of 'class or tedious'.
'first' acts as a link.
(Other definitions for assorted that I've seen before include "Of different kinds put together, say sweets" , "Manifold" , "Containing various different kinds" , "Various, diverse" , "Stared so at a varied mixture as of sweets" .)
