...it's bound to create some speculation.Yes, I'm sure it will feed the rumour mill, although possibly not to any useful end.
I won't breach anyone's confidence here, but I believe the health problems which prevented Paul from performing with Roxy at the Hall Of Fame induction ceremony have eased somewhat, so I don't think that is necessarily the reason for the split with Lindisfarne.
Mind you, I'm told that Lindisfarne had no drum roadie, so I'm glad that Paul no longer has to assemble and dismantle his kit either side of his performances!
There will doubtless be reignited hopes of some 50th anniversary gigs by Roxy, but my understanding is that any shows under the band name have to include BF, Phil & Andy. The last news on Andy's health problem (which affects some of his fingers) suggested, sadly, that we may not hear him play in public again.

I'd love to be proved wrong, mind you...
