Don't know why you say "A shame they didn't stay together longer." As far as I know they are still going (and for instance have appeared regularly at the Islington Folk Club over the years), though as all the members are involved in a lot of other projects I don't think they peform as a group very much. I have seen Jon Petter for example in a number of other bands in London folk clubs.

Best bet is to look at the their website: The Drones.
