I know that this issue keeps raising it's head and I have to say I'm absolutely with the majority view on this, but I find Appendix A [[the Musicians Union contract info) very interesting. There are a couple of queries too [[e.g. "I'm Ready For Love" MR&TV) but for the most part it confirms what most people say. What's more it gives recording dates for many of these tracks and, perhaps, points to some still being in the can? Seems like a decent piece of work to me.
