A supergroup in formation?

A respected member of the bluegrass scene in Ireland tells us of

... strong rumours going about that a new hard-driving bluegrass band of well known pickers in Ireland is soon to be announced.

This kind of rumour, of course, is bound to annoy those bands who firmly believe that such a band already exists, and it's ours, thank you very much. It will also annoy those of us who have not been asked to join.

Nonetheless, the BIB can't help being interested. Does anyone know the substance, if any, that lies behind these rumours?
