"A CD reissue was released in 1991 by Repertoire Records with two bonus tracks (REP 4178-WZ). It credits the band as "The American Amboy Dukes", the name under which the group's records were released in Britain."
So... We have a 5.th name now: "The American Amboy Dukes" - maybe that's why you don't have it yet?
Could you get it, please?
I'll write the record company too, but which is it you would like me to write? Is it the label that issued the CD?
