If you haven't heard, Ed Lee declared today Tony Bennett Day in SF. It's the 50th anniversary of Bennett's ode to our city, "I Left My Heart in San Francisco." The SF Boys & Girls Choruses and the SF Symphony performed the signature song at the City Hall Rotunda, and you might've caught it broadcasting over loud speakers in Union Square and Hallidie Plaza. To get in the mood, we put together a smooth Tony Bennett playlist to celebrate this historic, gorgeous day. Enjoy!

1. "It Had to Be You"

2. "Fly Me to the Moon"

3. "Body & Soul," from MTV Unplugged in 1994....incredible.

4. "I Left My Heart in San Francisco"

5. The Lady Is a Tramp," with Lady Gaga

And last but not least....a clip of our very own sing Tony Bennett sing along at the Chronicle Books building. Just another day at the office!
