Strange bard, a toff, is here with similar people (5,2,1,7)
I believe the answer is:
birds of a feather
'similar people' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'strange bard a toff is here' is the wordplay.
'strange' indicates an anagram.
'bard'+'a'+'toff'+'is'+'here'='bardatoffishere'
'bardatoffishere' is an anagram of 'BIRDS OF A FEATHER'.
'with' is the link.
Can you help me to learn more?
(Other definitions for birds of a feather that I've seen before include "Like people" , "sitcom" , "like-minded people" , "Likes" , "A kind" .)
