Bis are a Scottish rock band composed of Steven Clark (Sci-fi Steven), John Clark (John Disco), and Amanda MacKinnon (Manda Rin). Formed in 1994, the band broke up in 2003, reforming in 2007 for a series of concerts. The three musicians formed Bis in 1994, when Manda and John were in secondary school and Steven had recently finished. About a year later, they appeared on Top of the Pops performing Kandy Pop from their Secret Vampire Soundtrack EP ahead of its release, widely reported as the first such appearance by an unsigned act. Bis had a number of EPs that almost scraped into the UK top 40, including Sweet Shop Avengerz. In the late 1990s "Eurodisco", from the album Social Dancing, became a notable success for the band.
