Put on music that epitomises Ireland (8)
I believe the answer is:
shamrock
'that epitomises ireland' is the definition.
(the shamrock is a symbol of Ireland)
'put on music' is the wordplay.
'put on' becomes 'sham' ('sham' can be a synonym of 'put on').
'music' becomes 'rock' (rock is a kind of music**).
'sham'+'rock'='SHAMROCK'
(Other definitions for shamrock that I've seen before include "symbolic of Ireland" , "Symbol of Ireland" , "The national Irish trefoil" , "Clover-like plant" , "Pressed grape-juice" .)
