The Company of Snakes are half of what was the 'classic' Whitesnake lineup (Bernie Marsden, Micky Moody and Neil Murray) supported by Don Airey on keyboards, Robert Hart on vocals (ex-Bad Company, hence the 'Company') with a couple of drummers, depending on who happens to be free at the time.

As I write this it appears that Robert Hart has bowed out of the band to concentrate on writing his own material. More details from the Snakes Pages . The new vocalist is Stefan Berggren - also a member of Snakes in Paradise. Is there some connection?

These are the dates I've seen (links to finished reviews):

Bernie and Micky also perform shows as the Moody Marsden band and I hope to have a page or two about those shows sometime.
