John Daly proved once again he's always the life of any party -- the golf legend hopped on the mic and showed off his singing skills at an event with Johnny Damon ... and the performance was impressive!!
It all went down at Damon's Celebrity Golf Classic Sunday at the Reunion Resort Club in Kissimmee, FL ... and Daly provided plenty of entertainment for the star-studded guest list as he had a cigarette and beer in his hand.
Ken Griffey Jr., Alonzo Mourning, CC Sabathia, Plaxico Burress, and a slew of other high-profile names were in attendance for the bash .
