Steve Gardham, if are you referring to the early recording http://www.youtube.com/watch?v=E7Gs2pjpJvs>http://www.youtube.com/watch?v=E7Gs2pjpJvs Notes on youtube say it was recorded in 1918 (a few years after the expedition) by members of the crew. Mick Maloney played a bit of that recording in his introduction to the modern Ballad of Tom Crean by Cliff Wedgebury (Irish Arts Center youtube channel) but I don't think he said anything about the crew members being involved in the recording.
