I can't believe I'm the only one...
Anyway, I'm a member of a group named Mac-Talla in The Washington, DC area, ( The original one; not the secondary group in Scotland, now disbanded. ), and a past National Award winner, ( I took third place first time out at The Scottish Mod in Ligoner, PA a few years back tying with past gold medal winners, [ There's more to this story. ] ), and it would be fun to create a group here in Oklahoma too.
Most Old Traditional Scottish songs were sung A Cappella whilst the performer was working, ( weaving, cooking, spinning, harvesting, etc. ), as well as performed this way for dance music. Nothing stops a Scott. After our fiddles and pipes were taken away as instruments of war and of the devil, we sang "Mouth Music". If no one joins me, I'll still not stop. However, I don't allow audiences in the shower. ;o)
