Being a metal detector addict I can attest to the fact harmonicas were very popular around the campsites. All I find left are the brass reed plates. Along the railroad camps the large number of these plates makes finding other things very difficult. If you can find a tape or 33rpm of Don Reno & Red Smiley singing Civil War songs the lyric of the southern perspective is very interesting. POA...SCAW...For those of you who may want to teach Civil War songs to children, look for a lyric lesson elsewhere on this site in the song Two Little Boys. Frank
