world's oldest surviving band

I discovered recently that in April of 1996, the Guiness Book of World Records awarded Les Brown with the distinction of being the leader of the longest lasting musical organization in the history of popular music, "Les Brown and the Band of Renown". But Les died in 2001, so who or what is the current holder of the title?

I'd have thought that a church choir or maybe an orchestra or a military band would have got a better claim, even when Les Brown was alive, but maybe the Guiness Book of World Records was actually looking for a band with at least some of the same personnel as when it started.
