Taken from \"Pot, Spoon, Pipe And Jug\", the third in a series of themed blues/jazz LPs in the mid 1970s by US label Stash Records. http://www.discogs.com/label/Stash+Records The themes centred around sex and drugs, with tracks generally taken from 78s from the 1920s-40s.
In this case though, the track was taken from 1975, a year before the LP's release. There seems to be no info on the band, and they only appear to have recorded this one song. The cover states \"Plastic Jesus is a reworking of the famous WWVA broadcast jingle by a contemporary jug band.\"
