Winston, from Parow, was diagnosed with stage four kidney failure. The 47-year old vocalist is part of the band Encore.
The singer and producer collapsed on Saturday, 18 May, while he was watching his son play soccer.
He now only has 15% use of his kidneys left and needs an urgent transplant.
Winston needs treatment which cost up to R300 000 a year and is currently receiving dialysis four times a day to keep him alive.
The dad of three and his wife, Antoinette, were in awe of all the artists who came out to support them.
“It’s amazing how much love we are receiving from the artist performing here tonight,” a grateful Winston says.
“We are grateful for the support from all these people and want to thank Calvin Petersen for his role in bringing all this together.”
Salomé Damon paid special tribute to Winston with the hit song, This Is Me.
An emotional Salome said: “Winston, you will pull through, you are the music and we need you to survive.”
Calvin Peters, aka Uncle Cal, who is the custodian of the Band Aid project, says: “When the artists heard about Winston, they came on board immediately.”
Joining Salomé on stage were Claire Phillips, Leslie Kleinsmith, Vuvu Khumalo, Uncle Cal, Signature SA, Related Harmony, Just Us, Ramaine Barreiro, Jabez, Protégé, Naz Stage, Mr Magic, Niyaaz Goolam, Brandon Leigh from KFM and international star Choko from the Caribbean.
