I agree Malcolm. That is very sound advice. Also you run the risk of offending Irish or Scottish members in your audience if they misunderstand your intent and believe you're making fun rather than music. The tomes Malcolm recommends should be more than adequate. However if you want to get a feel for it Robert Burns wrote in Highland dialect and his poetry should give you fair insight to the Scots dialect. For the irish side of things i recommend you listen to see what the Irish folk singers are doing. I particularily recommend Christy Moore's stuff It's available on Green Linnet Records or his earlier work when he sang with Planxty, Reguards Neil
