half-back on topic of the thread.
reading the lawsuit from last year, it became clear that FM doesn't seem to exist as a legal entity between projects. they come together and sign contracts for specific projects - be that a tour, a gig, or in the past various albums and releases.
which means that at this moment, Fleetwood Mac as a band doesn't legally exist in any formation.
when talking about Fleetwood Mac, you can talk about Peter Green's band, various in-between incarnations, or the most well known Classic Fleetwood Mac - which is what masses are referring to when saying FM. but at present time, there is no present band. Lindsey is not really ex-FM member - or they all are.
