Wild about line in Get Back (7)
I believe the answer is:
salvage
'get back' is the definition.
(I've seen this before)
'wild about line in' is the wordplay.
'wild' becomes 'savage' (synonyms).
'about line' becomes 'l' (I am not sure about the 'about' bit.).
'in' indicates putting letters inside.
'savage' going around 'l' is 'SALVAGE'.
Can you help me to learn more?
(Other definitions for salvage that I've seen before include "Rescue of property as from fire or flood" , "Rescue (a ship from loss at sea)" , "Recovery of wrecks" , "Restore" , "Rescued material" .)
