"Joe & Eddie" from the 60's folk era. Not brothers but childhood friends & fantastic. "Clishmaclaver" & "Side By Side," both from the DC area - now split up- as well as "Sanders, Cass & White" from the 'Balmer area. As well, of course, as many already mentioned.. Like to hear some o' them recordings mentioned. Think I'll add this to my tracer list.Cheers, BK
