This was a handout for Dave's electric band in Liverpool circa 1969 which used to play blues and Cream numbers.
From the right they are: Dave Arnott (bass), Roy Cove (guitar), DE (guitar) and Jim (drums).
Thanks to Roy Cove who sent me the picture..
Dave Arnott has since contacted me and this is Dave today. He now calls himself Jake and plays with a band in the Bristol area called the Chain Gang. This has obviously remained his best side!
