John Mayer burst into tears remembering his friend Bob Saget while retrieving the late Full House star's car from the Los Angeles airport.
Mayer was accompanied by comedian Jeff Ross, who filmed the journey for an Instagram Live video.
Mayer and Ross were given the task of collecting Saget's Prius from an LAX parking lot, where the actor left it before flying to Florida for a comedy show. The 65-year-old actor was later discovered dead in his hotel room.
"I've never known a human being on this earth who could give that much love, individually and completely, to that many people in a way that made each person feel like he was a main character in their life and they were a main character in his life," Mayer said while driving the car.
"Everyone is so aware how universal Bob's love for people was.
"The thing that just keeps coming up when people say they're sorry is just, 'I loved that guy,'" the 'Gravity' singer continued through tears.

"He had every excuse under the sun to be cynical, to be upset, to be distrusting... but he laughed and he spread joy and his protest against the cruelty of these things was that he was going to smile, and spread love, and be childlike, and be innocent and be loving."
Mayer and Ross explained that they had to pay US$250 to have Saget's car released from the parking building, with Ross declaring he would be keeping the receipt in his wallet as a reminder of his late friend.
Ross said that Saget "really did take care of everybody", explaining: "If you need a doctor, if you need a lawyer, if you need a pastrami sandwich at three in the morning because some girl just broke your heart, Bob was that guy. He knew how to handle success and help people stay successful. He always gave me great advice."
Mayer added: "He is Santa Claus. He is bigger."
"I think he lets people have fun. You don't have to calculate why you loved him."
Ross and Mayer said they had spent the last couple of days with Saget's friends, family and much of the Full House cast.
Saget's cause of death remains unknown, but authorities announced they found no signs of trauma, foul play or drug use when responding to the scene.
