Back to the horses: I had to laugh at the commentator's description of what the Irish Guards were parading to, giving the impression that the 2 sets had been composed for the occasion: I think "arranged" is the word he should have used.
"Irish Saffron" included John Ryan's Polka, I'll Tell me Ma, and If you're Irish, come into the parlour. And
"The Mists of Shannon" was in fact The Cliffs of Dooneen followed by Spancil Hill.
