I remember a fragment of another song about the 42nd. It was on a Robin Hall and Jimmie McGregor LP. I only remember the chorus and a fragment of one verse. It went something like this.

Cho.
Wha saw the forty second?
Wha saw them gang awa?
Wha saw the forty second?
Marchin' doon the Broomielaw.

Verse fragment

Some were ......
Some were greetin' for their Ma
Some were ......
Marchin' doon the Broomielaw

At least that's what I can remember. I am pretty sure the LP concerned is still up in the loft, but I have nothing to play it on, so I can't check it just now.
