After months of recording – including sessions with producers Norwegian duo Stargate, Ed Case, Blacksmith, Rishi Rich, and Ceri Evans – Mis-Teeq finally released their debut single "Why?". Co-written and produced by David Brant, a remix version by Matt "Jam" Lamont soon became a success in the underground UK garage scene, and as a result a second music video for the song was filmed and released. While "Why" became a hit on the UK Singles Chart, with a peak position of No. 8, McNally decided to leave the line-up in spring 2001.
