Very keen to be entertained by bog-standard entertainers (6)
I believe the answer is:
ardent
'very keen' is the definition.
(I've seen this before)
'entertained by bog-standard entertainers' is the wordplay.
'entertained by' says the answer is hidden in the clue (the clue hosts or entertains the answer).
'ARDENT' is hidden in the letters of 'bog standard entertainers'.
'to be' is the link.
(Other definitions for ardent that I've seen before include "Fiery and passionate" , "Enthusiastic or passionate" , "passion" , "Passionate, full of feeling" , "Very keen" .)
