This release is identical to Grandmaster Flash & Melle Mel - White Lines (Don't Don't Do It) (U.S. Street Mix)
other than the labels are very different. Notably this one has a large "A" printed on Side 1.
This is a remix of the 1983 release with the same catalogue number.
The "B" side is labelled as one instrumental track. However, it actually runs seamlessly into a shorter vocal mix of which there is no mention on the label.
