Are you (if you're a U.S. resident) a Netflix member? If so, you might be interested to know that Netflix has Come West Along the Road, one of RTÉ's DVD compilations of music recordings from its archives.
Like a lot of compilations, it's a mixed bag. But there's some brilliant material on the DVD. There is (brief, unfortunately) footage of Frankie Kennedy, Mairéad Ní Mhaonaigh, and other Ó Maonaigh family members playing in a pub in Gaoth Dobhair. There's footage of Joe Cooley, Denis O'Brien (Donncha Ó Briain), Tommy Peoples, and Matt Molloy.
While I was watching one of the segments — it must have been Planxty or The Bothy Band — my wife came into the room and said, "They look like hippies!" I laughed and replied, "They are hippies; this was taped in 1973!"
Sure, most of this has been pirated onto YouTube, but the DVD quality beats the heck out of Flash video. I'm not sure I'd pay $30 for it, but getting it "for free" (as a Netflix subscriber) is a great deal!
