John Mayer rocked out in Chicago over the weekend and continued his journey west to meet up with his trainer in LA yesterday. He's still holding back his unruly hair with a bandana and sporting his new green Rolex Submariner though his red, black, and blue signature JM Silly Bandz were still on his wrist — the popular accessories aren't just for kids! John's been back on his grind enjoying the Summer, continuing to atone for his public goofs and sharing his highlights with Twitter and tumblr. Next up, John's heading to Arizona for tomorrow's show in Phoenix followed by a handful of performances in California.
