The two tracks were released to UK dance clubs in July 1987, with no artist or label credit. "Pump Up The Volume" proved to be the more popular side and was the track more heavily promoted (in particular, it was the track for which an accompanying video was produced) when 4AD released the 12" single (as, officially, a double A side) on August 24. It entered the UK singles chart the following week at number 35, a strong initial showing for an unknown act, especially on 12" sales only. However, what gave "Pump Up The Volume" its commercial edge was the remix released a week later. This remix became the best-known version of the track, transforming it by the addition of numerous samples which provided the record with additional hooks besides its oft-repeated title chant - Public Enemy shouting "You're gonna get yours!", the title line from Criminal Element Orchestra's "Put The Needle To The Record" (a minor house hit from earlier the same year), samples from The Bar-Kays "Holy Ghost", and most distinctively, a speeded-up sample of Israeli singer Ofra Haza's "Im Nin Alu". It was this remix, rather than the original, which was edited down to create the 7" version of the track, which began picking up radio play.

As the record climbed the charts, however, the single ran into legal difficulties. With "Pump Up The Volume" standing at number two, an injunction was obtained against it by Stock Aitken Waterman, who objected to the use of a sample from their hit single "Roadblock". Distribution was held up for several days while negotiations took place, which resulted in an undertaking that overseas releases would not include the "Roadblock" sample. Dave Dorrell later stated that he believed SAW would never have noticed the highly-distorted sample had he not rashly boasted about it in a radio interview. Many observers suggested that SAW's motives had just as much to do with extending the run of their production, "Never Gonna Give You Up" by Rick Astley, at the top of the chart. "Pump Up The Volume" went on to spend two weeks at number one in October 1987 and was also, minus the "Roadblock" sample, a hit in many other countries.
