Sessions at the Circle: Leslie Odom Jr.

‘John Lennon vs. the USA’ book talk
Immigration is a hot topic right now, but who is and isn’t allowed to stay in the U.S. is a debate that’s been going on since the country’s founding. And sometimes, the “offender” is not who you’d think.

Pianist Alfio will perform a special rendition of Lennon’s “Imagine.” Sept. 7, 7 p.m., 55 Fifth Ave.
