Remember to tip your servers, he'll be here all week.

Bill Murray serenaded the audience at his Caddyshack Restaurant in St. Augustine, Florida Friday night, performing a 45-minute set that included Van Morrison's "Gloria" and The Animals' "House of the Rising Sun." You go, Bill!

Murray launched the restaurant in 2001 with his brothers and was in town for the annual Caddyshack Celebrity Golf Charity Event. TMZ, of course, was on hand to capture the video, which you can see below.

Murray can be seen on-screen now in Wes Anderson's The Grand Budapest Hotel and next plays a cantankerous war vet in the comedy St. Vincent, which costars Melissa McCarthy and opens April 11.
