Jimmy Fallon clearly loves doing musical impressions, so when he had Barbra Streisand making a rare appearance on The Tonight Show to promote an album of duets, he took the opportunity to be the legendary singer’s partner. Alongside a bemused Babs, Fallon trotted out his Elvis, his Blake Shelton, and his Michael Bublé. During the Shelton section, a rendition of “I’d Want It to Be You,” Streisand tapped Fallon, and declared, “I can hardly tell the difference.” Before moving onto the Bublé she said, “That was actually good.”

Though she made a cameo on David Letterman’s Late Show in 1994, Streisand hadn’t been on The Tonight Show since 1963. “This is the first time in over 50 years you’re here, I think you should sit behind the desk,” Fallon said.

With Streisand seated in the host’s spot Fallon prompted her to reminisce about her previous late night visits with Johnny Carson and Orson Bean (apparently Jack Paar didn’t like her), and chatted about her diva reputation. “Divas were opera singers first of all, and how come they never call men divas?” she said. Streisand also didn’t let Fallon infringe on all of her stage time, performing a solo rendition of “Come Rain or Come Shine.”
