(Yahoo!) - When Justin Timberlake and Jessica Biel were married October 19 in Italy, the former 'NSync boy bander sang his bride down the aisle, crooning an original song that he wrote for the occasion, which left nary a dry eye in the house. However, when it came time for the couple's first dance, they relied on a classic tune — "A Song for You" by Donny Hathaway.
"A Song for You" is actually one of the most-covered songs in modern music history. Written and recorded by music legend Leon Russell, it appeared on his eponymous album in 1970. The love song seems on target for the celebrity couple as it tells the story of a famous singer who hopes to live up to the expectations of his lady love. Noting that they had been through some tough times ("I've treated you unkindly") — making us think of Timberlake and Biel's brief split — he says there is no one more important than she is, she's made him a better man, and he'll love her "for my life."
