Sound of bagpipes coming from runner on both sides (5)
I believe the answer is:
skirl
'sound of bagpipes' is the definition.
(I've seen this before)
'runner on both sides' is the wordplay.
'runner' becomes 'ski' (ski is a kind of runner).
'on' means one lot of letters go next to another.
'both sides' becomes 'rl' (I've seen this in other clues).
'ski'+'rl'='SKIRL'
'coming from' is the link.
(Other definitions for skirl that I've seen before include "Sound from pipes" , "some piping, we hear" , "Sound of e.g. bagpipes" .)
