Band at funeral threw a wobbly (6)
I believe the answer is:
wreath
'band at funeral' is the definition.
'threw a wobbly' is the wordplay.
'wobbly' is an anagram indicator.
'threw'+'a'='threwa'
'threwa' is an anagram of 'WREATH'.
(Other definitions for wreath that I've seen before include "Circular garland" , "Ring of intertwined foliage" , "Circle of flowers used at funerals" , "Funeral arrangement" , "Circle of flowers or foliage" .)
