I have seen the lyrics of 'Mining for Gold' [Trad/J.Gordon] as recorded by the Cowboy Junkies and James Gordon on several sites and they all give the following as the last 2 lines of the first stanza:

Pour your bottles on our shoulders
We are marching to the slow

Can someone elucidate these lines for me? I can find no definition of 'slow' as a noun and am mystified by the reference to pouring bottles on shoulders. The mining glossary that was available on the Internet seems to have disappeared.
