While "I Wanna Be The Only One" might be their most fondly remembered — particularly the version performed with BeBe Winans on Top Of The Pops on Christmas Day, 1997 — their debut "Stay" (released just a year after forming) was a stunner in its on right.

Featuring the original line-up that included sisters Easther and Vernie Bennett along with Kéllé Bryan and Louise Redknapp (although Louise left before their debut album dropped), "Stay" struck at exactly the right moment, capitalising on the US-dominated New Jack Swing sound and reminding the world that the UK had plenty to say in the R&B conversation.

Here they are, all four of them, the very same year on Top Of The Pops, setting the scene for what would be a near decade-long career that included 12 Top 10 singles, a Number 1 single and a Top 10 album. In other words, they proved themselves to be a bit more than just the UK's answer to En Vogue.
