London: Robbie Williams is set to sing at his father`s wedding reception on May 1.
Pete Conway, a club singer, performed at his son`s own marriage ceremony in LA in 2010 and now Williams will be returning the favour, the Mirror reported.
The 39-year-old singer will perform at his country pile in Wiltshire after his dad ties the knot with South African Melanie Mills , who is also 39.
The couple met through the Donna Louise Trust, of which the former `Take That` star is patron and Mills is the head of fundraising.
Conway, who proposed during a trip to Malta in 2012, said that his son is so pleased for him after his engagement.
The 64-year-old asserted that Mills and he had been together for two years so they thought that they`d get engaged and the next thing was to plan the nuptials.
