'Single Ladies' is Tom Hanks' favorite song

Actor said it is his tune of the year 'because it's infectious'

NEW YORK -- Tom Hanks is down with the single ladies.

Hanks first racked his brain when asked for his favorite tune of 2009 while backstage at the Rock and Roll Hall of Fame's 25th anniversary concert Thursday.

Then, the song came to him -- though he didn't know all the words.

"Dada-dada ring on it! Dada-dada ring on it!" he sang, as he tried to remember.

"That is a damn fine song, the Beyonce song ... because it's infectious," the 53-year-old actor said of Beyonce's No. 1 smash, "Single Ladies (Put a Ring On It.)"

Hanks said "Single Ladies" resonates with him because that's what he told his wife, actress Rita Wilson, when they first met: "I'm gon' put a ring on that finger. I'm gon' take that thing home."

He also joked: "Kanye West has nothing to do with my embracing of that song."
