They don't really do the whole song. They sort of use it as an intro to "Rock Island Line." It's on a live album called "Ain't It Grand Boys." I don't know who thought up the title of the album; it should be "Isn't It Grand Boys."It's a really good album. It's got a good version of "The West's Asleep" as well as "Auld Triangle". Both are done a cappella.
Thanks for the info. I'll definitely check out the Weavers.
