Well thanks for volunteering to tackle the CDs Jordan!!!!

(seriously... any other recruits to the cause would not be discouraged!)

What we have, across the Fame label on all formats, and as far as it fits into the schemes of MFP, CFP, Captiol, and EMI, is several impossibly difficult jigsaws, which, when complete, will be themselves, only pieces of a larger jigsaw.

But if headway is made on one aspect, you can use it to see how it relates to the other bits, which could be helpful. The abandonment of the 41-1s (4s on tape) on vinyl surely has something to do with this.

...which establishes one set of facts, and raises another question: We know that the 1 at the end of the vinyl cats is vinyl format, and 4 is tape, so we can say that 2 must be CD format signifier.

...but then, what on earth could 3 be?

(wherefore art thou 3?)
