Us Weekly reports that some well-known musicians played the reception as well:
According to eyewitnesses at the star-studded event, [John] Mayer played "Daughters" as Parsekian, the co-CEO of Finding Kind Productions, danced with her father.
"Aaron came out back after John sang and caught him before he left to shake his hand and say, 'Hey, thanks for doing that man, that was great,'" an onlooker told Us Weekly. Mayer didn't stay long after his set. Foster The People also performed at the fun-filled celebration.
