Chas, You must have been sending that clip as I was writing my reply.I do have a different version, but it is almost a copy of this clip.
Harry Bluff allegedly mimicked other artists and this would prove this point.Harry's version is much brighter than this ,but the backing band etc is almost identical with the arrangement and still no concertina.
I will see how I get on with the words or give someone else the job.
