Sorry to hear about Weiss. I, too, knew about The Lion Sleeps Tonight/Wimoweh. I think Pete Seeger also dealt with the issue of whether or not that was a traditional song. However, Weiss did many good things for music. Here's (I hope) a link to the NY Times obit: http://www.nytimes.com/2010/08/24/arts/music/24weiss.html
