If it's on Leader then it's Bulmer . . and also your description matches that I've heard of other Bulmer re-issues.
Geoff and Richard: My understanding is that all legal angles have been considered and are always under review by at least some of the parties involved.
Certainly there have been a couple of cases where artists have re-recorded work that's locked in the Bulmer archive . . while these have been close to the original they've not been "note for note" - a wise decision, IMO, since you can't recreate a "cut" you made 20 years earlier, and attempting to do so is probably doomed to failure.
If CM has gone out of business I'll lay money the Dave Bulmer trading as something else has acquired all its rights to everything. The guy is, without doubt, a shrewd business man. I deliberately failed to mention his re-imaging some of his operations (e.g. I've seen the Clan Alba double CD marketed on a flyer which makes no mention of Bulmer or "Celtic Music").
