Abayomi Sydney Onayemi (3 November 1937 – 1 May 2016), also known as Big Brother Sydney, was a Nigerian-born Swedish disc jockey. His other name "Abayomi" means "he brings me joy and happiness" in the Yoruba language. Onayemi came to Sweden in 1962 to study finance at the prestigious Stockholm School of Economics. After two years he had to drop out of school due to lack of money. In order to pay his bills he started working at restaurants, mainly cleaning bathrooms at the Strands Maritime. Eventually he started deejaying soul, and later funk and disco, music that was fairly new to Sweden. He also sang along to the tracks, added maracas and other live percussions. In 1972 he opened his own discothèque Big Brother.
