Pretty much a mystery, I'm afraid. Thanks to Robert Bowes who kindly sent a scan along I can report that a band called Chalkie put out what appears to be a self-financed single, 'Rock Me Angel', in 1978. There's no company identity on the label, so I've given it the same name as the band; as they went to the bother of providing a logo and a picture for it the least I can do is name it after them. The catalogue number, DT-003, isn't any help - similar series were used by custom recording concerns DTS and Beck (q.v. both) but they had gone a long way past 003 by 1978. Any information about the single, or about DT-001 and 002 if they exist, would be welcome.
