Tony Bennett And John Mayer Sing 'One For My Baby' (VIDEO)

Tony Bennett has had his fair share of star-studded duets in recent months, and now he's taken the stage with a suit-clad John Mayer.

The 85-year-old singer, who released his Grammy-nominated album "Duets II" in August, performed an old-fashioned rendition of "One For My Baby (One More For The Road)" alongside Mayer on Bennett's PBS special "Tony Bennett: Duets II" on Friday night.

Whether or not it has to do with his spunky duets with musicians like Mayer, Lady Gaga, and Michael Buble, the "I Left My Heart In San Francisco" singer shows no signs of slowing down.

"You should always keep going," Bennett told The Huffington Post in September of last year. "I like that philosophy. Because the people I've met, that retired, they regretted it. They're looking at wall and they don't know what to do with themselves."
