Long, poetic old record, I see (4)
I believe the answer is:
epic
'long poetic' is the definition.
'epic' can be an answer for 'poetic' (thesaurus). I am unsure of the 'long' bit.
'old record i see' is the wordplay.
'old record' becomes 'EP' (abbreviation for extended play record).
'see' becomes 'C' (the word for the letter, according to Chambers).
'ep'+'i'+'c'='EPIC'
Can you help me to learn more?
(Other definitions for epic that I've seen before include "Of heroic proportions" , "Tale of heroic deeds" , "Marathon" , "blockbuster" , "Large-scale" .)
