Somebody mentioned (in 2013) That Ronnie Ross (real name Ron Melia) had three son's, actor Joe Melia wasn't his son. I'm Ron Melia's Granddaughter and my mum said they often used to laugh about it as they were asked a lot. Both of Ron and Peg Melia's sons are in the film also.
Ron passed away in 1990 and Peg in 1999.
