Record overseas epic poetry (4)
I believe the answer is:
epos
'epic poetry' is the definition.
(I've seen this in another clue)
'record overseas' is the wordplay.
'record' becomes 'EP' (abbreviation for extended play record).
'overseas' becomes 'os' (abbreviation).
'ep'+'os'='EPOS'
(Other definitions for epos that I've seen before include "One has many lines" , "Things sold here" , "body of poetry" , "Epic poem; electronic point of sale (abbrev.)" , "Verse" .)
