TMZ spoke to multiple employees at the H.D. in Rancho Mirage, CA., who tell us Tyler randomly picked up the microphone on Saturday and belted out snippets of "Dude Looks Like a Lady" and "I Don't Want to Miss a Thing" for all the weekend warriors to enjoy.
And get this: We're also told Tyler took a hit from a helium machine and kept singing Bee Gees style while signing autographs for anyone who asked.
Coolest. Guy. Ever.
