Get together in the flesh, say (4)
I believe the answer is:
meet
'get together' is the definition.
(I know that get together can be written as meet)
'flesh say' is the wordplay.
'flesh' becomes 'meat' (flesh is meat).
'say' shows a homophone (sound like).
'meat' is a homophone of 'MEET'.
'in the' is the link.
(Other definitions for meet that I've seen before include "Get together socially or for business" , "Come together or run into" , "Fitting - encounter" , "Come face to face with - it is proper" , "sporting occasion" .)
