When Robbie was born, his parents ran a pub called 'The Red Lion' in Burslem, Stoke-on-Trent. Robbie's parents divorced in 1977, when Robbie was three years old. After the divorce, his dad - Peter Clive Williams - focused on his career as a stand-up comedian and singer and became an entertainments manager at Carmarthen Bay Holiday Village (Kidwelly), Holme Lacy House (Hereford) and seven other locations. When Robbie was on his summer holidays and whenever Pete was doing a summer season on a show, Robbie used to be backstage and watched the entertainers. Robbie had an idea when he was 10 or 11 years old "That's what I want to do". Pete tried to discourage Robbie, but also knew from when Robbie was a small child, he had the "X Factor".
Pete also was a licensee at the Port Vale Social Club. This led to Robbie's life long affinity with the football club. Pete married the 25 years younger Melanie Mills in 2013 in one of Robbie's mansions. Unfortunately the marriage didn't stand and the couple got divorced in 2018. Since 2015 Pete joins his son on tour and sing one song together on stage; either Better Man or Sweet Caroline. Conway is a stage name. When he became an entertainer, Pete decided to use the last name of one of his good friends; Conway. The last years he's commonly known by the nickname "Poppa Pete". In February 2018 he joined twitter with the handle @poppapete299
In 2019, Robbie released the album "The Christmas Present", which contains a duet with his father; It's a Wonderful Life. Pete announced his retirement during The Robbie Williams Christmas Show; the special gig in Stoke-on-Trent in June 2020 would be his last performance. Unfortunately the concert was cancelled due to COVID-19. In 2020 it became publicly known that Pete has Parkinson's disease.
