Elton John Performs Live At Free Surprise Sunset Strip Concert (With A Surprise Guest!)

WEST HOLLYWOOD (CBSLA.com) — Elton John performed a free concert at noon Saturday at the site of the old Tower Records store on Sunset Boulevard.

The singer made the announcement Friday night and again Saturday morning on his official Twitter account.

The performance, at 8801 Sunset Blvd., was streamed live on AOL.

The 68-year-old pop star released his latest album earlier this month, titled "Wonderful Crazy Night."

Speaking of surprises, John was joined on stage by Lady Gaga, close friend and godmother to the singer's two children.

CBS2's Greg Mills was at the concert and talked to many of the excited fans. There were 10,000 people, according to the Sheriff's Department.

The legendary performer told lots of stories, like performing for the first time in Los Angeles 46 years ago.

He played "Your Song," which brought Lizzie Szabo to tears.

"It's one of my favorite songs," she said.

As for favorites, John played most of them.

"Elton John! Never seen him better. I saw him at the Wiltern and he's even better now," said Brent Kendall.

The concert might have been the worst-kept secret in town. Except area resident Scott Weisman had no idea it was happening.

"I was trying to get my sleep this morning. All of a sudden, a neighbor starts blasting Elton John," he said, "and I'm slowly trying to figure out what the hell is going on. I was going to yell at my neighbor. And I came [out here], and he was my neighbor. Singing for us."

The concert lasted for little more than an hour.

John said he played the concert in West Hollywood to thank the city for its long-standing support of his Elton John AIDS Foundation and his post-Oscars party.
