Neat article..... but maybe a bit misleading concerning Rock and Roll.
Here is a bit more info on Lt. Thomas Couzens.

"As a young boy I was an avid reader, revelling in stories of daring and adventure, and in the boy's magazines and comics of the 1960s, I first saw pictures of the Tucker Sno-Cat. (Made by the Tucker Co. of Medford, Oregon).
These were used in Sir Vivian Fuchs' Trans Antarctic Expedition of 1956/7. Four of these vehicles were used by Fuchs' team, nicknamed "Rock'n'Roll", "Haywire" and "Able". The fourth,
"County of Kent" was lost forever in a crevasse, along with its driver, Lieutenant Thomas Couzens.
These vehicles, dragging heavy sledges, made the first crossing of the continent, coast to coast. Crevasses were the greatest danger, yet somehow, they all except Lt Couzen's vehicle, were recovered from the brink. It looks a severely troubling (original words deleted!) activity to me." --
