Blodwyn Pig were a British rock group founded by Mick Abrahams after he left Jethro Tull in 1968. (Abrahams had a major falling out with Tull leader Ian Anderson.) Blodwyn Pig consisted of Abrahams (guitar and vocals), Jack Lancaster (saxophone), Andy Pyle (bass guitar), and Ron Berg (drums).
These are photos from concerts where Blodwyn Pig played, so they may be of other bands that played the concert as well.
