Scored this lovely mint promo of this David Ruffin heater infamously covered by @bittymclean_silentriver courtesy of Chris @groovemerchantsf. The 12-inch promo of this trades for a couple hundred bucks, but the 45 was the one I was looking for and doesn't show up often either. I've been collecting Motown demo/promo 45s for a while. I've always heard that the Motown promo 45s were pressed at a higher quality than the commercial releases. This logic holds true for many of the major labels during the 1960s and 70s. My next trainspotting endeavor is comparing promo copies to commercial copies of crucial Motown 45s for noticeable difference in the fidelity. Some people say the promos were the first pressed off of stampers so they sound better, but I'm not convinced as I don't think over usage of the stampers in the US was much of an issue compared to other regions. When records hit for Motown, label owner Berry Gordy often used multiple pressing plants to meet demand, so my guess is it's a song-by-song situation.
