Guys, it's not "Swinny Moore" as I heard last time, and a few times before that on the flat.
It's "Soon Uh Morr".
The 'oo' to sound like the "Oooh" as in "Oooh Aah Cantona".
It means "The Sound of the Sea" in Welsh and should actually be spelt "Swn-y-Mor", with a circumflex over the 'w', but Betfair text doesn't I think allow that.
