The song scored #2 in the UK Singles Chart[1] earlier in 1983 before reaching the top of the BillboardHot Dance Club Play chart in the U.S.,[2] giving them their only chart-topping single on any chart in America. It then became the 20th best-selling single of 1983 in the United Kingdom. "I.O.U." was used for the 1984 breakdancemovie, Beat Street. The chorus is often erroneously sung by listeners as "A-E, A-E I-O-U, and sometimes Y", referring to the vowels of the alphabet. It is actually "A-E, A-E, I-O-U, U, I sometimes cry" and "A-E, A-E, I-O-U, U, I sometimes lie".
During 1986 a 12" single was released in the US by the Criminal Records company, with new remixes. Some of these remixes were given a re-release during 1987 in the UK for the Citybeat label as "I.O.U. (The Ultimate Mixes '87)", however, it only scored #23 in the UK Singles Chart this time.[3]Dancer in video Michael o'shaughnessy
