Welcome given to Jagger? It's a bit icy (9)
I believe the answer is:
hailstone
'a bit icy' is the definition.
(I've seen this before)
'welcome given to jagger?' is the wordplay.
'welcome' becomes 'hail' ('hail' is a greeting or welcome).
'given to' is a charade indicator (letters next to each other).
'jagger?' becomes 'Stone' (Mick Jagger is one of the Rolling Stones).
'hail'+'stone'='HAILSTONE'
'it's' is the link.
(Other definitions for hailstone that I've seen before include "bit of a storm" , "a drop of the hard stuff?" , "one in the shower" , "Frozen pellet" , "sign of cold weather" .)
