What if Julie Andrews sang Jessie J's hit "Bang Bang"? What if Celine Dion sang Sia's "Chandelier"? What if Barbra Streisand, Kristin Chenoweth, Alice Ripley, Patti LuPone and Bernadette Peters teamed up for "Ring of Keys"? Wonder no more! Singer and impressionist Christina Bianco will answer these (and many other!) musical questions in her upcoming show at Birdland called Party of One. She will share her musical influences and her love of the great divas. Performances are on both Sept. 20 and 21. See show details.
