Saints supporter here (and a very excited one at that) also in Basel but I'm off to watch it at the Aussie bar in Munich, and then on to Oktoberfest...
However, I've heard they will have it at Paddy's and Mr. Pickwick's, you just need to call them and ask. There's probably enough Aussies in Basel for them to warrant having it on (and they'd definitely have it on)!

GO SAINTS!!
