Isn't Liebman just a couple of days later the same week? I didn't even realise Sechseläuten was on 8th - early this year...Playing at Sechseläuten on Potter night, but got tickets for Liebman the following week and Sanborn in May.
I'm sure you already found the link, otherwise tickets available here: https://www.starticket.ch/de/tickets/three-wise-men-scott-hamilton-20190301-2000-salzhaus-bruggWhat?? I get tons of emails advertising all sorts of music and have been waiting for a Scott Hamilton concert for ages. Can't believe I've not found out earlier. Thanks!
