"Doctor Jones" was the fifth single to be released by the Scandinavian dance-pop group Aqua overall, and the second UK release. The single is their second United Kingdom number one. The follow-up to their most successful song "Barbie Girl" in many places, "Doctor Jones" was a similarly pop-oriented hit which sold well across the globe and ended the assumptions that Aqua would be a one-hit wonder. In Japan, "Doctor Jones" was released along with "Lollipop (Candyman)".
