Does anybody remember watching a Youtube video of Martin Carthy and Dave Swarbrick singing a jaunty music-hall type song?

It was an old video recording, B&W, and they were both very young. As I recollect, Swarb was sitting on the floor, playing mandolin, and they both sang.

The video appears to have been removed from Youtube, but if it hasn't, and I am just being incredibly inefficient at tracing it, I would be most grateful if anybody could supply the URL.

TIA.
