Paul Shaffer, the Canadian singer and former bandleader for "Late Night with David Letterman," was on the keyboard to produce a stirring rendition of the Star-Spangled Banner before Vegas' game at T-Mobile Arena.
Shaffer, 68, displayed his signature soulful voice and delivered a Vegas-worthy performance. The former Grammy Award winner was Letterman's sidekick for 33 years and is in Las Vegas for a limited run performing with his band the Shaf-Shifters at Caesars Palace.
