Clock was a British band primarily led by Stu Allan and Pete Pritchard. They started as a house music British "2 Unlimited" when they recruited rapper Marcus Thomas (using the name ODC MC), and vocalist Lorna Saunders (using the name Tinka) to front the act. Thomas left in 1998, to join the band Tzant, to be replaced by Ché-gun Peters.
They had hits with more covers (nine) in the 1990s on the UK Singles Chart than any other act. They also released hardcore versions of their hits under the name Visa.
In the early 2000s, Saunders appeared on BBC Television's Never Mind The Buzzcocks in the celebrity line-up. It was announced that she was now working as a legal secretary.
