Anton, known as Dode, and Anne Dolderer, celebrated their golden anniversary with a party in the Taxi Club.
Instead of gifts, the Coldside couple asked family and friends to contribute to the Not in Vain for Lee charity.
Lee Welsh took his own life, aged only 27, claims he had not been given enough support for mental health issues.
Since then his family have been raising funds in his memory.
Lee’s childhood friend Steve Martin, 27, organised the first Lee Welsh Memorial Match which was held at North End Park in June. It will be played again next year.
Lee’s dad Phil said: “Our friends Dode and Anne requested that their guests contribute to the Not in Vain for Lee charity events which will take place again in the summer of 2019.
“They raised a massive £750 at their special party and have donated this to us.
“This fantastic gesture will enable us to buy a second set of strips for the memorial match next year and still leave money to go towards our chosen mental health charity.
“We cannot thank them enough for this amazing gesture.”
