Independent label: DRG Records Apparently DRG was a manufacturing firm, based in Hereford; for some reason it released a single purporting to be a response to a letter of appreciation from one of its customers. I presume the record - 'DRG Boogie' by Big Wal & The Wyetainers - was given away for promotional purposes, rather than intended for sale. Both sides feature the same performance. Thanks to Robert Lyons For The Info.
