Other older British bands in that same kind of vein would be The Albion Band, Show of Hands, Fairport Convention, Jethro Tull, Lindisfarne and Pentangle. If you're feeling masochistic then try Steeleye Span, but I don't recommend it.

Depending on your guitar ability, you might also want to dig out stuff by Davey Graham, John Renbourn, Richard Thompson and Bert Jansch. "Anji" by Davey Graham is generally a rite-of-passage for fingerpickers.
