Leon Russell starts off Elton John concert

Before Leon Russell performed, Elton John walked on stage and warmly introduced him to the audience.

"Four years ago, I toured America with my idol," John said. "It was one of the greatest experiences to be on the same bill as him. Here we are 40 years later and we're doing it again."

Then John talked about his album with Russell was No. 3 on the Billboard charts and "we're so happy."

Next, Russell went into "Tightrope" to a cheering audience. The sound, at least from the press box at the top of the area, was a little muffled but as his set went on the sound improved. Russell also performed "Prince of Peace/Out in the Woods" "A Song For You" and "Roll in my Weet Baby's Arms" among other songs to lots of applause.

When Russell finished, he simply walked off the stage. John is next.
