“He would have been amazed to see you turn out for his birthday…His fans – there’s nothing like you…Thank you all, thank you grandparents, for passing his legacy down to young kids,” Priscilla told the crowd.

Lisa Marie brought her four children, Benjamin Keough, actress Riley Keough, and twins Harper and Finley Lockwood, to the event, and they all led the crowd in a performance of “Happy Birthday” for the rocker.

“There’s really nowhere else we’d rather be,” Lisa Marie told the crowd.
