The memorial wasn’t something we’d heard about before PigletsDad’s post and a little googling revealed the origins of the memorial itself was something of a mystery as this media item from 2011 indicates.
More inquisitive mouse clicking reveals the memorial, in the shape of a bass clef, was made by sculptor James Parker who reveals that it was commissioned by Boz’s widow, Cath.
You can view the piece on James’ flickr page and these photos taken by Hugh and originally posted on the Black Cat Board.
