Google music recognition app failed to identify it.
It is usually quite reliable.
So this gem seems to be a really obscure track as far as online data bases are concerned...

Perhaps other similar apps might recognise it...???

It sounds too polished for a demo,
- maybe a well recorded extremely rare private pressing..???

Or could be one of the myriad of shelved and forgotten undocumented fully mastered out-take tracks
denied release by philistine record lable managers...?????

btw..Thumbs up for even a micro second fragment of a Rare Bird track,
one of the best bands ever imho...
