Making an appearance at 4:01, in the light grey suit, is Bob's son Robert, later known as Bob Paisley Jnr.
Some years ago, I used to sit next to him at the place I then worked. He never talked openly about football but would reply when asked. He once told me that the club wasn't especially friendly towards him or the other family members like they had been in the past. He thought it was the changing face of the club and all the money involved. This was around 2004, a few years before Moores sold up to Hicks and Gillett.
