Bundle of Covid tests for '60s entertainers? (3,4)
I believe the answer is:
rat pack
'covid tests for '60s entertainers?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'bundle' is the wordplay.
I cannot quite see how this works, but
'bundle' could be 'pack' (pack can mean a bundle of items) and 'pack' is found within the answer.
The remaining letters 'rat' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Another definition for rat pack that I've seen is " Paparazzi as a group".)
