I've never seen Pete Seeger in concert but have found him to be a profound influence on my singing and politics for a long time. I should be at the Girvan Folk Festival that weekend and I know there is a talk and show by Alastair Hulett planned on Pete Seeger for that weekend.
Hopefully it'll be on that day but I am certain there will be many of "his" songs (although I am convinced they are everyone's in reality) sung that weekend.
