Query: a unique combination of progressive rock with folk

I discovered this band quite by accident back in 73 after buying Bursting At The Seams on a whim, as I had heard that this was the band that launched Rick Wakeman's carreer just b4 he joined YES. This is by far the best of their more pop oriented material. Dave Cousins is one of the best lyricists in folk or rock. He could be very spiritual, funny, and sometimes downright snide and accusatory. if you're not familiar with The Strawbs, this is a great place to begin.
