San Francisco Honors Tony Bennett on St. Valentine's Day

Cupid now has to share 14 February with legendary crooner Tony Bennett in San Francisco - city officials have renamed St. Valentine's Day Bennett Day in his honor.

Mayor Edward M. Lee presented the I Left My Heart In San Francisco singer with the key to the city during a public ceremony at City Hall on Tuesday - to mark the 50th anniversary of the song, which Bennett first performed during a concert at the Fairmont Hotel in 1962.

Bennett returned to the venue on Tuesday night to relive his magical moment all those years ago.

And to further mark the anniversary, every San Francisco radio station played I Left My Heart in San Francisco at noon on Tuesday.

Emotional Bennett was blown away by the tribute and he wiped away tearsas a children's choir performed an a cappella rendition of his famous tune.

The singer said, "I've never seen anything in my life as beautiful as these young people".

He told fans that he never thought the song would become an international smash hit "I always thought it would just be a local song, in this area".
