To the in the jungle tune:
We are Scotland,
We're Bonnie Scotland,
We're going to win away,
We are Scotland,
We're Bonnie Scotland,
We're going to win away,
Aaaawwwwwaaaaaaaaaayyyyyy, we're going to win away,
we win away, we win away , we win away, we win away.
We are Scotland,
We're Bonnie Scotland etc etc.
Away can be changed for again for home games but doesn't fit quite as well.
