Beggars Opera were a progressive rock band from Glasgow, Scotland, formed in Glasgow in 1969 by guitarist Ricky Gardiner, vocalist Martin Griffiths, and bassist Marshall Erskine. The band's fourth album Get Your Dog Off Me was originally issued on Vertigo Records in 1973 (and it was their last release on the label) and the artwork from that album is now reproduced on a high quality earthenware mug.
