You could hear the Cubs clubhouse well before walking into the new state-of-the-art facility.
On Cinco de Mayo, of course Joe Maddon's Cubs would have a live mariachi band - complete with a Cubs jersey - performing as players geared up for a showdown with the NL East-leading Washington Nationals.
What were you expecting - Maddon wearing a sombrero?
"I can confirm I won't be wearing a sombrero in the dugout," Maddon joked before Thursday's game.
Fresh off their "Minimalist Zany" suit trip that included a sweep of the second-place Pittsburgh Pirates, the Cubs are feeling themselves quite a bit, so the mariachi band actually fit right in.
Plus, it made for a pregame moment Maddon said he'll remember forever.

"I was partially serenaded in the video room," Maddon said. "They were really good. My favorite moment was their solid rendition of 'Tequila' that was resonating throughout the entire clubhouse.
"It's something I'll probably never forget - hearing a mariachi band playing 'Tequila' and your boys really participating pregame. That was kinda fun."
Maybe if the Cubs win Thursday, they'll celebrate with shots of Patrón.
Here's to hoping they dump the contents of a margarita machine onto a players' head during the CSN postgame interview. It'll be just like the "slime" on Nickelodeon.
