Tony Bennett turned 90 earlier this year on, and bunch of stars including Stevie Wonder, Bob Dylan, Elton John, Aretha Franklin, Andrea Bocelli, Billy Joel, Lady Gaga, Alec Baldwin, and Kevin Spacey put on a concert a few weeks ago to honor the legendary crooner. The Tony Bennett Celebrates 90 concert aired last night on NBC and featured both actors and musicians covering their favorite Tony Bennett songs. Baldwin opened the night with an impression of Bennett that got laughs from the singer himself, then Gaga got the performances rolling with a rendition of “The Lady Is A Tramp.” Bennett closed out the night with three songs and was joined onstage by everyone as they sang him “Happy Birthday.” Watch the full concert below.
