It seems that the term 'traditional' changes throughout the ages. Who would have thought at in the halicon days of Irish Harp music that the accordian would have become such an intregal part of the Irish tradition? The same, I think, applies to the guitar. Players such as Arty Mc Glynn etc have made it a viable instrument for playing instrumental music and who could find a better version of Arthur McBride than Paul Brady's, in which the guitar calls the shots.

Its when computers start to generate music that I would become worried

A mediocre guitar player
