" I.O.U. " is a song from 1983 by British musical group Freeez, their most successful hit. The song scored #2 in the UK Singles Chart earlier in 1983 before reaching the top of the Billboard Hot Dance Club Play chart in the U.S., 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 breakdance movie, 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 I sometimes cry " and " A-E, A-E, I-O-U I sometimes lie ". The music video for " I.O.U. " featured on the video version of Now 1 but the song itself did not appear on the album version. Read more about the song
