Tony Bennett won over generations of fans crooning "I Left My Heart in San Francisco." And on his 95th birthday, the beloved singer left his heart on the stage of Radio City Music Hall. Six months after Bennett and his family revealed he is suffering from Alzheimer's, Bennett sang alongside Lady Gaga before sold-out crowds in a two-concert series in early August billed as his final New York performances.

Now the rest of the world has a chance to take in the moving August 3 show in a TV special, "One Last Time: An Evening With Tony Bennett and Lady Gaga," which aired Sunday on CBS. In addition to his signature song, Bennett performed standards like "Fly Me to the Moon" and "Steppin' Out With My Baby" and duets with Lady Gaga including "Love For Sale" and "Anything Goes."
