To try and a little more,
Yes John Anderson had these twice, when he sold them to me and when I sold them back to him mid-late 80's.
The scan above is a complete supprise to me, never seen that one before or heard of it. Could be real, as to say anything is a one off is always a dangerous thing. But looking at it, the light clean part of the label going across on the studio address part, with none of the staining that is visable on the rest of the label looks odd.
Need to see the disc really to make any more comment. Being credited to M-Pac or another disc being credited to Toddlin' Town, no great suprise. I collect studio disc's and the info on them can often be incorrect or scant, the guys cutting them were not always the shapest knife in the box. Often they were cut with no info at all and later someone would scribble a bit of info on. Many have no label at all and spotting fakes can be real hard. You need to know where they come from, the story behind them, but none of it is a perfect science.
But there are ways of telling, many major labels use just one or two mastering companies for there discs and a few had there own machines and labels. Many of the Detroit independant artists used Ron Murphy or Bob at The Disc, both used the same company for their blanks. In Philly many would use Frank Virtue and they appear with his mastering label on.
All of it just adds to the colourful world of collecting hard to find tunes. So as of today I would have to say the only two discs that have a fully confirmed history are the ones John has for sale. Good luck to all bidding and John, I'll be popping my promotional bill in the post
