White demos purpose was to demonstrate the record to the public, primarily through radio station plays. Since there was no point in spending more than necessary on something that was never for sale, the cheapest paper for a label is white and the cheapest ink for the print is black. Of course, some issues of records where black and white labels too.
They weren’t given away as they always to remain the property of the record company. Most were, if unsuccessfully making the song a hit, either binned or given to the local thrift shop. If they were a hit they remained in the radio station’s library and played, rather than being substituted by an issue (as being sold in the shops) copy. Hence only issue should end up with a drill whole, not WDs.
The Drew records out of Detroit seem to be on styrene WDs and blue issues. The label number prefix is ‘D’, Sidrian Music BMI, plus a ZTSC number
Instant Heartbreak is on vinyl and distributed through Laurie Records of New York. The label number prefix is ‘DR’, Ardis Music BMI, W4KM – 0326 - - 1 ( Same format ** KM - **** - - * as other NY label records, such as Carl Spencer – Cover Girl) Perhaps Mike Terry had a deal with Laurie (before or) after he moved from Detroit to NY?
