Beggars Opera bootleg recordings are from 1972.
 
They included singer Martin Griffiths and Pete Scott, who replaced Martin, in 1972.
The recordings of Martin are from a gig in Germany* and Cardano al Campo, Italy was the venue which recorded Pete Scott.
The quality is poor but it is interesting to feel the vibration of the live band.
 
12 Tracks included in this download.
 
*this is not the Germershiem Festival recording, which is of singer Gordon Neville who stood in at the last minute when Martin left Beggars Opera.
